With a search engine's help, you can locate individual appearances of such words in documents all over the Web. Most sites that offer search features contain elements of both kinds of organizational schemes. Often the fastest and simplest method of finding particular sites is to simply enter the site's name, or terms describing it, into the search box and let the engine do all the work. However, if your not sure where to find what your looking for, or you want to survey a broad range of information on a topic, a more informed use of the search engines and directories is often helpful. In general web directories are most useful if you have only a general idea of what your looking for and Search engines are better if you know exactly the kind of information you want, or the information you want is very specialized and unlikely to fit into a neat category.
Most search engines sort the results of a search in some way.
If the results of your search returns a thousand, or, many times, several thousand matches, the ones the search engine believes are the most pertinent to your topic will be displayed first. Many times the search engines do a good job of returning the information you need. Most search engines will return pages that contain ANY of the words you include in their search with the ones that include ALL of them at the top. This will cause the search engine to return only pages that match ALL of the terms in your search. Would find pages that have all three of the words on them.
