If you don't know a web site for the topic upon which you need information, however, you have to resort to a search engine, such as Altavista, Excite or Lycos, listed above. A few tips to improve your search efficiency follow. Choose your search terms carefully. The more specific your words, the better your results. Use quotation marks.
Most search engines recognize anything within quotation marks as a phrase.
Use connectors to limit your search. Many search engines use boolean logic. Thus, the terms AND, OR and NOT can be used to specify whether certain terms must, could, or must not appear in the document in order to be returned in the search. When all else fails, read the instructions. Search engine sites usually have a help or search tips section that will give much valuable information to help you to use the capabilities of that search engine to improve your search.
