Searching the Web





Search engines index billions of web pages and put them at your fingertips. Google is best for all-around searching, but you may prefer other engines for specialized searches or if Google doesn't do what you want. (No one engine knows about every web page.) Some engines, such as Teoma (www.teoma.com) and Open Directory (www.dmoz.org), have their own spin on analyzing and organizing relevant links. You can find search-engine recommendations, news, tipsand about everything else you'd want to know about the subjectat www.searchenginewatch.com.


To search by using Google:




1.


In your browser, go to www.google.com (Figure 13.8 ).




Figure 13.8. Click the Preferences link to set your language(s) and the number of search results to display per page.

2.


Type a search phrase in the box; then click Google Search.


Google responds with a list of links, ordered by relevancy (Figure 13.9 ).




Figure 13.9. Search engines are fast. Here, Google's results bar shows more than 3 million matches for


human genome project in about a fifth of a second. Search engines rank pages by using proprietary (and competing) "relevance" formulas; Google's is called PageRank.

3.


Click any result link to visit the page.




Tips


To bypass the results list and go straight to the most relevant page, click I'm Feeling Lucky (instead of Google Search) in step 2.


To increase the accuracy of your searches by adding operators that fine-tune your keywords, click the Advanced Search link (visible in Figure 13.8).


The Google toolbar adds a search bar to IE that lets you search from any web page (it also blocks pop-up ads). The Google Deskbar adds a search box to the taskbar. Get themand other free search toolsat www.google.com/downloads.


Google's simple interface hides a lot of features and sophisticated technology. Click the About Google link (visible in Figure 13.8) and browse the Our Search section for help, search features, services, and tools.




You also can use IE's Search Companion to search the web.


To search by using Search Companion:




1.


Click Search on the toolbar (or press Ctrl+E).



2.


Type a search phrase in the text box; then click Search (Figure 13.10 ).




Figure 13.10. The search results appear in the pane to the right of the Search Companion.






Tips


Search Companion uses MSN Search by default. To use a different search engine, click Change Preferences (in Figure 13.10); click Change Internet Search Behavior; select With Classic Internet Search; select an engine; then click OK.


To search directly from the Address bar, press Alt+D; type go, find, or


? , followed by a space and a search phrase; then press Enter.


After you go to a web page, choose Edit > Find (on This Page) or press Ctrl+F to search for specific text on that page.


Beware of advertisements posing as "sponsored links" interlaced with results. Reputable search engines like Google color-code paid links or set them apart from legitimate results.


A


metasearch engine or


metaengine queries other search engines and compiles the results that it receives. Try www.dogpile.com or www.vivisimo.com.


A good alternative search bar is Dave's Quick Search Bar (free; www.dqsd.net).






.comBAT



When you search for information about health, science, weather, scholarly disciplines, government services, high culture, charitable causes, not-for-profits, news, and religion (not shopping, sports, or celebrities), favor .org, .gov, .edu, and other noncommercial domains over .com sites. A comparison should convince you: Visit www.weather.gov (the U.S. government's National Weather Service site) and www.weather.com (The Weather Channel's commercial site), and behold:



The NWS site loads quickly, has no ads, shows only weather information, uses graphics sparingly and effectively, plants no cookies, has an obvious search function, and shows a clear map of nationwide weather and warnings.



The Weather Channel site greets you with pop-up ads; has banner ads that occupy substantial screen real estate; plays Flash animations; is inundated with sales pitches, self-promotion, and slow-loading images; plants a cookie; and has one tiny weather map.




Google's site operator can help you. To search for, say, philosophy pages at only educational sites, use the query philosophy site:edu. To search at only United Kingdom academic sites, use philosophy site:ac.uk.
