Understanding Searching

How can you find what you're looking for? If you are looking for something on the Web, chances are you will use a search engine instead of plodding through dozens or hundreds of pages in hopes of uncovering items of interest. These search services are made possible by programs known as robots, spiders, Web crawlers, or worms; they are on the job 24 hours a day, 365 days a year. They do nothing but wander around from site to site, reading and cataloging whatever they find. They store the results of their searches in huge databases, which anyone can access.

That's the easy part: assembling the haystack. But how to find that needle? This section examines search techniques used by search engines to sift through masses of information to bring back results that satisfy your request.
