More growth results from making your own effort rather than asking others to make the effort for you. I didn't say, don't ask questions. The material below is eleven years old. Take it for what it's worth and excuse spelling errors. Chapter 23 Google As Research Tool By Michael R. Cross
In the chapter on the internet, I used the Google search engine to download antivirus and anti-spyware programs, but Google can be used for more general types of information gathering. This chapter discusses several ways you can use Google.
23.1 Basic Searches
There are two basic general-purposed searches, the "Search" button and the "I'm feeling lucky" button. They both process data that you enter into the "Search edit:" box. There are also some specialized searches such as the "Frugal" button. Both types are described in the paragraphs below.
23.1.1 I'm Feeling Lucky Button
If you are absolutely certain that you have the best set of search terms, and that you only need to look at the page that Google gives the highest relevancy ranking, then you can activate the "I'm feeling lucky" button. Since there is only one resulting web site, Google doesn't bother to build a result list; it just puts the PC cursor inside that web site. As this happens, JFW will announce the web site's title. For the search query "University of Texas", activating the "I'm feeling lucky" button connects immediately to "University of Texas at Austin - Web Central", the official University of Texas web site.
23.1.2 Search Button
The "Search" button is usually the button most beginners use to kick off their web searches, and lots of users never use any other button. When you do, Google generates a result page containing a list of web sites related to your search query. This list varies according to the search terms with which you started the search. In fact, even if you simply type the same search terms but in a different order, the results list could be different. The pages on the list appear in decreasing order of relevance as determined by the Google search engine. However, web masters have a little control over how close to the front of the result list their particular web site appears. There is a brief discussion of this at the end of this chapter. There are actually two results lists. The first is a list of web sites that have paid to be there. Google makes it clear that these are not the actual search results by putting them under the heading "sponsored links". Each result in the search results list has four parts. The first is the actual link. JFW announces it as both a link and a level 2 heading. The second part is an excerpt from the page itself. This excerpt will contain your search terms or maybe a synonym of one. The third part is a line that says, "cached." Google saves snapshots of pages in its cache. If the site in the results list is currently unavailable or has been removed from the Web, activate the Cache link immediately below it. You will connect to the snapshot, which may be an out-of-date version of the page. Finally, the fourth part is a line that says "similar pages". As its name suggests, this is a link to sites with similar content.
23.1.3 The Search Edit Box
Life is full of forms, and the web is no different. Conducting a search with Google begins with filling out a form called the "Search edit:" box. To start a search for information on any subject, type into this box one or more words describing what information you are seeking. These words (or phrases) are referred to as "search terms", and taken collectively they are called the "search query". The outcome of your search query is a dynamically generated page called the "result page". It is a page that contains a list of web sites that Google determines to be related to your search, either directly or indirectly. The more specific the search terms in your query are, the more likely the web sites in the result list will contain the information you seek. Press INSERT+UP ARROW to hear where the PC cursor is on the Google web site. If it isn't on the "Search edit" box, press the letter F to move to it. This keystroke actually moves the PC cursor to the next form on the page, but since it is the only form on the page, pressing the letter F always works. That is, no matter where the cursor is, this keystroke always relocates it the "Search edit:" box. You can't type any search terms into this form until you enter "Forms mode. Do that by pressing the ENTER key. JFW will say, "Forms mode on". Now you can type your search terms. As you compose queries, stick to lowercase characters because Google is never case sensitive. In all search queries, it converts uppercase characters in your search terms to lowercase. So, for example, you may as well type the word "American" with a leading lowercase 'a'. The results will be the same whether you do or not. Exit forms mode by pressing the PLUS key on the numeric keypad. JFW will say, "forms mode off". Next you will tab down (or maybe up) to a search button and press the SPACEBAR. Google processes your search, and focus moves to the results page. As discussed in the previous two sections, the way Google processes the search query depends on which button you activate. As stated earlier, supposedly, the most relevant page is at the top of the list, and in general the more specific the search terms in the "Search edit:" box, the narrower the scope of the search and the more relevant the subject matter contained in the web pages given by the result list will be. Adding another search term to the "Search edit:" box usually narrows the scope of the search. You want to have enough terms in your search to narrow the scope of the search, but not so many that Google refuses to process it. I recommend not having more than eight search terms in your search query. Depending on the topic you are investigating, your queries may be shorter and in rare instances longer. Use your intuition, and be prepared to conduct more than one search to achieve the result you want. Activating the "Search" button moves the PC cursor to the "Sign in" link on the search results page. To see the links that Google flagged as being objects of your search, you will have to cursor down to the results list.
23.1.3.1 Constructing A search Query
There are some basic rules to follow when composing a set of search terms. Don't include words or phrases that are vague. Be brief and to the point rather than wordy. For example, don't type, "help for people that can't see". It would be better to type "blind employment" or "Blind rehabilitation" or "Blind independent living" or "Blind travel skills". Your search term should include nouns, especially place names or titles. Also include any adjectives that distinguish the topic or object being sought. Google will put the web sites that are described by all your search terms early in the results list. As you cursor down through a list, you start encountering sites that are described by some but not all your search terms. You might also encounter web sites that didn't contain one of your search terms but one of its synonyms instead. When this happens, the synonym will be highlighted in the excerpt of text below that link in the result list. This means more to people who are watching the screen as well as listening to JAWS read. Avoid putting conjunctions, prepositions, and articles in a search query, for example, the words "and", "but", "from", "to", "in", "into", "a", "an", and "the". Google will also ignore common words such as "where" and "how". Also avoid single digits and single letters; they don't help the search. If Google omitted a word in your search query, you will find a message about it on the result page beneath the "search edit:" box. For example, I typed the search query "into every life some rain must fall". Google ignored the preposition "into". Here's a portion of the result page. into every life some rain must fall Search
Advanced Search Preferences
Web
Results 1 - 10 of about 1,450,000 for into every life some rain must fall. (0.10 seconds)
Tip: Save time by hitting the return key instead of clicking on "search"
Henry Wadsworth Longfellow Quotes
Henry Wadsworth Longfellow Into each life some rain must fall. ... Each morning sees some task... - Every man has his secret. ... www.brainyquote.com/quotes/quotes/h/henrywadsw139003.html - 20k - Cached - Similar pages. Notice a few things. At the end of the line that begins "results 1 - 10 of 1,450,000" are the words "For into". Google ignored "into" the first search term. There was a surprise! Google supplied the preposition "For". I had forgotten that "for" was part of the quotation. Google supplied it as one of the ignored search terms. The fact that "into" didn't appear as part of a link tells you that the word "into" was left out of the search. The other search terms appear on lines by themselves and JFW says "link" as you cursor through them. This tells you that these search terms didn't get left out of the search. IN contrast, the word "into" did not appear on a line alone and JFW didn't say it was a link. This means it did get left out of the search. Remember that Google tries to match your search terms against key words provided by web site owners. The fact that Google found a match in a particular web site does not however guarantee that your search terms occur close together or in any specific pattern on that page. In other words, there may be a relationship between the search terms in your search query, but the pages identified by Google as matches don't necessarily contain those words with the same relationship between them. For example, I entered the search "blind bus driver". When I looked at the web sites on the result page, one contained a story about a blind woman riding a bus. The bus driver who was not blind said something to the blind woman at the end of the story. My search string implied that the bus driver was blind. However Google didn't assume that blind was an adjective modifying "bus driver". In a second search, I typed into the "Search edit:" box the string "blind bird watching". Among the web sites identified by Google was one containing a story about a duck blind. Another site had a story about a group of blind people in natural preserves listening for recognizable birdcalls. The question arises "is there a way to force Google to look for groups of words in a specific relationship"? The answer is "yes". In order to force Google to search for web sites about a blind bus driver, type the search string "blind bus driver" enclosed in quotation marks. The quotation marks mean that Google searches for web pages containing the exact phrase rather than words "blind", "bus", and "driver" which may be scattered throughout the web page. It must search for the exact phrase "blind bus driver".
23.1.3.2 Search Operators
Google allows you to tell it how to organize and use the search terms in a search query by including special terms called operators in the query. These aren't really search terms, and that is indicated by the fact that on the results page, the operators don't occur on a line thar is a link. Examples of operators are the word "OR" in upper case and the word "site" followed by a colon and a website supplied by the user. Here are some of the operators available to you with either the "I'm feeling lucky" button or the "Search" button.
23.1.3.2.1 The PLUS Operator
I described above a method for forcing Google to search for pages with an exact phrase in its contents. There is a second method (although not as intuitive) of having Google search for an entire phrase. It is to put plus signs between the search terms in the phrase. The plus signs must be preceded and followed by spaces. For example the search query "absolute + power + corrupts + absolutely" works as well as "absolute power corrupts absolutely" enclosed in quotation marks. You can apply either one of these methods to force Google to include a term in your query, even when you aren't looking for an exact phrase. So, if Google ignored one of your search terms that you think is critical to getting the results you want, you can force Google to include it in the search by preceding it with a space and a "+" sign.
23.1.3.2.2 The "OR" Operator
You can search for pages about two or more categories of information using the "OR" operator. The pages in the results list must satisfy either the part of the search query that precedes the "OR" operator or the part of the query that follows the "OR" operator. And in the case where there are two or more "OR" operators, the pages in the result list must satisfy at least one of the parts of the query separated by the "OR" operators. Pages that satisfy every part are also included in the results list. As a test, think of two categories that you wouldn't expect to appear on the same website. Try this search query: "tigers OR gardening". As expected, the result list included links to sites that discussed either tigers or gardening, but not one listed that discussed both. In the list was the homepage of the Detroit Tigers. Notice that the word "or" was upper case. If it had been typed as lower case, it would have been treated as just another search term and not a directive to the search engine about the relation between parts of the search query. Try typing it in lower case. You won't get the same results. In fact, under the "Preferences" link, Google makes a suggestion to you. It is "Try uppercase "OR" to search for either of two terms. [".As you examine the results page further, you will notice that the word "or" appears on a line that isn't identified as a link. So, it got left out of the search. Actually, it would have been left out of the search whether it were upper or lower case. If it is upper case; it is an operator, not a search term. If it is lower case, it is a common word that Google omits from searches. Next prove to yourself that you can use the "OR" operator more than once in a query. Type "tigers OR gardening OR planets". What results did you get?
23.1.3.2.3 The Synonym Operator (tilde)
The tilda is another operator that tells Google to search for either the term or synonym of the term that is preceded by a ~. The use of ~ lets you construct the broadest possible search query. For example, try the query "~rehabilitation ~information". I found this interesting website among the results. Facts and Statistics for Rehabilitation Engineering and Technology ...
REHABILITATION ENGINEERING & TECHNOLOGY PROGRAM. (Department of Mechanical Engineering) ... FACTS AND STATISTICS. VR Status at Referral ... retp.eng.usf.edu/about_us/facts_and_statistics.htm - 28k - Cached - Similar pages
23.1.3.2.4 The Exclusion Operator (Minus Sign)
Another search operator is the exclusion operator, the minus sign. Suppose one of your search terms has meanings in more than one area, and you would like to avoid one or more of those meanings. In your search query, the term that has multiple meanings should be followed by a minus sign and a meaning to be excluded. For example, suppose you want to search for pages about pizza recipes, but not American, Italian, vegan, or vegetarian pizza. The search query "pizza recipes -American -Italian -vegan -vegetarian" would give you the results you want. Notice that you can stack up negative search terms, but if you end up excluding a long list of meanings, it may be time to rethink your search strategy. Remember the KISS principle; keep it simple stupid. Don't resort to the exclusion operator unless a straightforward query failed to give you the results you wanted. The search query "web surfing" is better than "surfing -waves -games -beaches -supplies -schools -tours".
23.1.3.2.5 Numerical Range Operator
There is a numerical range operator that looks like an ellipsis but with two periods only. To search for pages that span a numerical range your search query should contain two numbers separated by two periods (no spaces). Don't forget to include a search term indicating units such as pounds or inches. A search query for screen readers in the price range $10 to $200 would be "screen readers $10.$200".
23.1.3.2.6 Definition Operator
The definition operator is a little different from those presented so far. Rather than being an enclosing operator like the quotation marks or a binary operator like the plus symbol which stands between two parts of the query, the definition operator is a unary operator meaning that it doesn't stand between operands (parts of the query). Unary operators are either prefixes or postfixes. This one is a prefix operator, and it looks like this "define:". Your search query is the word "define" followed immediately by a colon and the word or phrase whose definition you are seeking. For example, to find a definition of the term "Braille", type the search query "define:braille". Google will display a collection of definitions of "braille" drawn from different sites around the web. On the day I executed this search, Google produced the following results: Related phrases: louis braille braille embosser braille display 9969 braille braille music braille book

23.1.3.2.7 Site Operator
Google allows you to restrict your search to a specific domain, that is website. In your search query, type your search terms followed by "site:" and the name of the website. For example, to get admission information at the University of Texas at Austin website, your search query should be "admission site:www.utexas.edu".
23.1.3.2.8 File Type Operator
Your search queries can specify pages containing documents in particular formats such as "txt", "doc", "pdf", "rft", "html", and others. This is done using the filetype operator. When you View a page in the result list, you will be given the option to view the document as HTML. Since the other document formats can carry viruses, it may be safer to cut and paste the HTML rather than downloading a document in one of the other formats. Place the filetype operator at the end of your query followed immediately by a colon and the format you prefer. Suppose you want to see a 1040 form in PDF format. Your search query will be "form 1040 filetype:pdf".
23.2 Advanced Search Button
The "I'm feeling lucky" button and the "Search" button both process the search query in the "Search edit:" box, but the "Advanced search" button doesn't. Instead, it sends you to a page whose title is "Advanced search". The page has several controls giving you much more control over the way Google processes your search query. You will notice that controls on web pages are very much like those in the Windows operating system, however You will notice one difference between controls on an internet website and those in Windows. On a website not just an edit box requires you to enter forms mode before setting its value, every control does. Combo boxes etc. all require entering and exiting forms mode. Depending on what kind of control you want to exert over the query, you will put different parts of the query in different controls. There are thirty-three controls falling into nine areas, some of which have defaults. These defaults are well thought out and often don't need to be touched at all. You can specify that pages must satisfy the properties in any or all of these areas. The first control on the "Advanced search" page is an edit box. The JFW keystroke INSERT+TAB announces the name of the control. It is "With all of the words". The search terms you type into this box are required to be on every page in the results list. The second control is a combo box with five entries. When you tab to it, JFW announces the name of the entry that the combo box is set to. It usually says "combo box 10 results. Its other four values are 20, 30, 40, 50, and 100. To change its value, turn on forms mode by pressing the ENTER key. Use the up and down arrow keys to move to the value you want, and then exit forms mode with the PLUS key on the numeric keypad. The third control is the "Search" button. The fourth control is an edit box called "With the exact phrase. Whatever phrase you type into this box is exactly equivalent to the phrase enclosed in quotation marks in the basic search discussed on 26.3 above. Obviously you don't need the enclosing quotation marks. This exact phrase will be on every page in the results list. The fifth control is an edit box named "With at least one of the words". The page in the results list will contain at least one of the search terms you type into this box. The sixth control is an edit box name "Without the words". The search terms you type into this box will not be on any of the pages in the results list. This is like the exclusion operator (minus sign) discussed earlier. The seventh control is a combo box named "Return pages written in". It has thirty-seven entries. The first, its default, is "All languages". This doesn't restrict the result list pages to be in any particular language. As with any combo box, turn on forms mode and use the up and down arrow keys to change the value. Press the letter E and the PC cursor jumps to English. The eighth control is a combo button called "File format. Its first value is "Only", and the second it "Don't". The ninth control is a combo box called "Return results with the file format". It has seven values, the first of which is "Any format". If the value set in the previous control were "only", then this control specifies what formats are acceptable for results page. However, if the value of the previous control were, "Don't", then this control's value specifies what format are not acceptable for results pages. The tenth control is a combo box named "Return web pages updated in the". This is a "fill in the blank" kind of control, and the value set in the combo box fills in the blank. Its four possible values are "Any time", "past 3 months, "past 6 months", or "past year". The eleventh control is an edit box named "return web pages containing numbers between". This is equivalent to the "Numeric range" operator discussed in 26.3 above. Type in the first number of the range. The twelfth control is an edit box for the second number defining the range. The thirteenth control is a combo box named "return results where my terms occur". This is another "fill in the blank" control where the values fill in the blank. The possible values are "anywhere on the page", "in the title of the page", "in the text of the page", "in the URL of the page", and "in the links to the page". The first includes all the others. The fourteenth control is a combo box named "Domain. It has two possible values "Only" and "Don't". Like a combo box you have already seen above, the value specified here dictates how to interpret the domain name you type into the next control, an edit box. The first value means "look only at pages on the following domain whereas the second value ("Don't") means "Don't look at pages at the following domain". The fifteenth control is an edit box named "Return results from the website or domain". Whatever website address you enter here is interpreted according to what you specified in the previous control- either accept it or block it. The sixteenth control is a link named "More information". The seventeenth control is a combo box name "return results that", and its two values are "not filtered by license", "free to use or share", "free to use or share- even commercially", "free to use share or modify", and "free to use share or modify - even commercially". The eighteenth control is a link named "more info". It is about the license filtering. The nineteenth control is a combo box named "SafeSearch", and its two possible values are "no filtering" and "filter using SafeSearch". The default is "no filtering" If you specify "safesearch", the result pages will be free of x-rated material. The twentieth control is an edit box named "Find pages similar to the page". If you have a page in mind, you can specify what the pages in the "similar pages" part of the results page will be similar to. The twenty-first control is the "Search" button that when activated will start the processing of the "advanced Search" information about your search. The twenty-second control is an edit box named "find page that link to". What you type into this edit box is a web address. The results list will contain pages that link to it. The twenty-third control is another "Search" button that processes all the information you entered into the "Advanced Search". The twenty-fourth control is an edit box named "Book search". The twenty-fifth control is an edit box named "code search". Activating this link sends you to the "code search" page. A result in this case is not a website but rather a file. Depending on what you want, this file will contain either the definition of a software function, or a computer program's source code. You can control the search by specifying file name, computer language (such as C++), and type of license (such as GPL). In addition, you are given more powerful ways in which to specify any of these things. In an earlier discussion, I said that the Google search engine didn't assume a relationship between the search terms you type into the "Search edit:" box. Remember the example about the query "blind bus driver". In performing a code search, you can force Google to look for those search terms in a specific relationship. Your queries take the form of something called regular expressions. These expressions describe textual patterns within a document or within a long string of text. The search actually opens files and examines them hunting for a match to the regular expression you specified. The searches described earlier in this chapter hunted for a match within a database entry for a website. The site itself isn't searched. This is a big difference. Obviously regular expressions have no place in the website searches. The programmers in the reading audience can look into the details for themselves, and for everyone else, this is more than enough said on the topic. The twenty-sixth control is an edit box named "Google scholar". The twenty-seventh control is an edit box named "Google news archive". Activating this button links to the "News archive Search" page. This is good for historians and those writing a historical novel. The edit box "Create a timeline which shows selected results from relevant time periods" is where you specify what historical event you are investigating. For example, type "Berlin wall". Then tab to either the "Search archive" button or to the "Show timeline" button and activate it. The results page is fairly straightforward. Some of the articles have an associated cost, but most are free. Have fun researching. The twenty-eighth, twenty-ninth, and thirtieth controls are "Apple Macintosh link", "BSD Unix link", and "Linux link". These controls are off topic and won't be discussed. The thirty-first control is "Microsoft link". Although this is very much on topic, it won't be discussed. The thirty-second control is "U.S. Government link". This is a very large topic and won't be covered here. The thirty-third and last control is "Universities link".
23.3 Two More Important Searches
It is important to be familiar with two more types of searches. The first deals with searches producing an overwhelming number and variety of results. It is a search within a search. The second, although interesting to all readers, will be especially valuable for education and research. It is a book search.
23.3.1 Search Within Results
Earlier I gave an example of having too many exclusion operators in a search query. Here's a better approach. Suppose my original search query had been simply "surfing". My results page has lots of links for ocean surfing and other topics too. There is a link on the results page close to the bottom called "Search within results". Bring up a links list with INSERT+F7 and type the word "search". By the time you strike the letter A, focus will have jumped to "Search within results". Press the ENTER key and you will find a blank results page with a form field called "Search within results edit". The search term you type here produces a results page extracted from the current results page. For example, in the "Search with results edit:" box, type "internet". The next results page won't contain any of the links to ocean surfing pages.
23.3.2 Book Searches
Google also helps you find books on a specific subject. For example, you can enter "books about blindness." At the top of the Search results page, you'll get a list of book results. Click on the Book results header to get a complete list. Or, an abbreviated list appears below it. When I executed this query, I got the following results. This is only a partial list.

Use the search queries: "books about DARPA", "books about World Wide Web", and "books about Tim Berners-Lee".
23.4 Nonuniqueness Of Search Results
Adding search terms that don't appear on anyone's meta-search list obviously don't help. In fact, it would insure that the results page is empty, because Google only puts a web site on the results list if that site satisfied all your search terms. Obviously you can't know what is on any web site's meta-search list. Neither Google nor any other search engine is exclusively responsible for the search results. Otherwise search engines would have to examine an entire web site to determine its relevance to your search. This would be so time consuming that it would bring everything to a screeching halt. Instead, each site's web master decides how he or she wants to advertise the site to search engines like Google. The key words and phrases picked out go into a list of terms called "metasearch terms". Search engines collect these meta-search terms from websites and store them in their databases. Then when you perform a search, Google uses its database to build a results page. It doesn't visit any website while building a result page. This is much faster than trying to evaluate an entire site. Websites have to apply to be included in Google's search engine database, and there are rules to be followed if a webmaster wishes his site to remain there. There are three factors that make it likely that a Google search performed today may generate different results than the same query performed a year from now. First new websites are added to Google's database. Secondly, some websites are removed from it. Thirdly, websites update their meta-search terms. All search engines periodically go through their list of subscribing websites, evaluating website content and updating their own databases.
23.5 Google Accessible Search
There are two web pages you should try for a more blind friendly experience. The first is: "http://www.google.com/ie";. This version of the Google Search page is for use on Personal Digital Assistant devices, PocketPC, and mobile phones. They have screens necessitating abbreviated results pages. This means only page titles and no accompanying description text. This is very attractive to many blind users. There is a "Search edit:" box and a "Search" button just as in the standard Google search. I executed the search query "lime marmalade recipes" with the following results page: Google lime marmalade recipes
Search I'm Feeling Lucky
1. Marmalade Recipes - Home Cooking 2. Lime Marmalade Recipe - Home Cooking 3. Lime Marmalade Recipe | Recipezaar 4. Lime Marmalade Recipe - Jellies and Jams Recipes 5. SURE.JELLR Lime Marmalade Recipe 6. Nikibone.com - Marmalade Recipes 7. Cooks.com - Recipes - Lime Marmelade 8. Astray Recipes: Lime marmalade 9. Guidelines for Marmalade Making > ABC Melbourne > Recipes 10. Lime Marmalade Recipe Next > images/toolbarsmall
The simplicity of the result page layout is very refreshing. There are no lines saying "Similar" or "cached" pages. Since I hardly ever activate them, their absence doesn't bother mea a bit. When I searched with the query ""http://www.google.com/e, the first website on the result page had the following comment under it: Bare-bones interface which returns only page titles. The website itself had only a "Search edit:" box, a "Search" button, and an "I'm feeling lucky" button. The second Google search page you should investigate is at "http://labs.google.com/accessible/";. It performs a search whose results rank sites high that are blind friendly. When Google gets a site's meta-search terms, it also evaluates its HTML source code. A good evaluation earns that website a high accessibility ranking. This accessible search puts the inaccessible pages at the bottom of the results list. So, you can still get to them; they are just not presented at the top of the results list. The result pages are less cluttered than the result pages on the standard Google search page. That in itself is a big help to the blind. Generally, what considerations go into an accessibility ranking? The pages that get high marks are those that "degrade gracefully"- meaning pages that would display well with graphics disabled. For the partially sighted user, the screen shouldn't be cluttered with cute but nonessential images. In fact, images are baggage. If images must be present, they should have text labels called ALT tags. More important are keystrokes and page structure. Can you do everything by keystroke that others can do with a mouse? Are the major sections of a page organized by headings at different levels? If the answer to these two questions is yes, finding the information of interest on a page will be much easier. I never go back to pages that trap you. They disable keystrokes like BACKSPACE and ALT+LEFT ARROW that allow you to return to the previous page. These web sites should be thrown out of Google's search database. The last straw is when you can't even turn on the JAWS cursor and simulate a left mouse click on the "Close" button at the right end of the title bar. Since the JFW configuration manager allows you to disable graphics and inline frames, graphics on a page hardly ever bother me (with some important but rare exceptions). I am more appreciative of the fact that the Google Accessible Search insures that the pages at the top of the results list support all the necessary keystrokes. Even using the standard Google search, most web sites on the results page seem to have a complete keystroke interface. Google is in a strong position to be an advocate for the disabled. Its most valuable service to the blind community would be to insist that all the web sites applying to be included in its search database must strictly follow the Web Content Accessibility Guidelines. Google should also raise objections to any attempt to change the World Wide Web Consortium in ways that would prevent accessibility.

Well, we are talking human nature here I think. its always easier to ask somebody who has gone further down the road than you, what is around the corner.
Google searches can of course be very misleading due to the way some web sites cheat by adding invisible pointless words so Google sees it, even when inappropriate.
Remember many people using computers early in the learning curve do not use " or: etc very well in searches either. and even if they do, still sometimes the item you want is not obvious.
Also as we have said before here, some find googles blunderbuss approach dodgy as you can, sometimes pick up some very dubious links on there that
are best left unclicked.
I'd also say that most people should add ad blockers to their browsers and
then many of the cluttering you encounter go away. Until advertisers learn to make adverts not compromise access to an accessible web site this is the only way I can work. Sad since I know the ads pay for the sites, but then I'm not the idiot designing stupid animations and scrollers and other graphical rubbish for
a basically textual sites adverts. Brian

Hi. A quick query. Lately, I have realized that most persons subscribed to this list, rather than going to Google or a search engine of their choice, seek
to ask questions here prior to doing this type of research. I'd seriously
like to know why, as I find this practice to be counterproductive. Why do
I say this? Because sometimes, the responses that are given are incorrect. Why don't persons read the NVDA User Guide, for example. It is well detailed.
Could persons explain this to me?
