Don’t confuse a web browser (a software program that helps you find, display and read a variety of document types) with a search engine (a web site that collects and indexes content from a vast array of Internet websites). A search engine sends its spiders to crawl the web and bring back page images to the search engine, which then indexes their content – therefore, when you search, it is NOT in ‘real time’ but is rather time-delayed, based upon when that search engine’s spiders last captured the web page and when that page was last indexed by the search engine! [For more detail, I recommend “How Does a Web Crawler Work?”
For the sake of brevity, I’ll limit myself to the “Big 3” search engines: Bing, Google and Yahoo!. When you search the Internet, do you use BASIC search?
BASIC searching is just that – it’s basic! It doesn’t take advantage of a wealth of limiters (if you read my Boolean search blogpost , you know that these help to refine your search or narrow its scope.) BASIC searching is great for a quick definition, the weather, an address or phone number, or a currency conversion, etc.
ADVANCED searching, however, will give you a smaller, more targeted result set. But your favorite Search Engine might not make ADVANCED Searching easy for you to do.
Why not try a variety of search tools? I’d suggest you add Best Search Tools to your favorites. [More on MetaSearch and Subject Directories to come, folks.]
And, for descriptions of their database contents, Boolean and other search options, look at Search Tools Chart Insert search tools chart here
You’ll be on the road to smarter searching!
