4 Search and advanced Search features Choose Words Carefully Use specific words to describe exactly what you're looking for. More general terms will give a larger number of results, so try to narrow your search. For example: try: "19th century chairs" instead of "old furniture" use: "digital camera reviews" instead of "electronics" Make sure to watch for words with more than one meaning. If you're looking for information on modeling, make sure you specify "fashion" or "clay."

5 Search and advanced Search features Search Engine Features: Math Commands Including Words: The + symbol, requires that a search engine finds pages that MUST include the words you enter. Example: Dog +cats If you want to see pages about the latest "in thing, search for "+in" thing." Excluding Words: The symbol, makes sure that a search engine finds pages that has one word but does not include another word. Example: +clinton lewinsky. if you want to see pages about dogs with no mention of poodles, search for "dogs -poodles." The quotes symbols make sure that a search engine finds pages that have all the words and in the exact order.

8 Search and advanced Search features (continued) Boolean Commands The Boolean search commands have been used by professionals for searching through traditional databases for years. Using the Math Commands is a good alternative. The OR command is used in order to allow any specified terms to be present on the Web pages listed in results. If you're equally interested in two or more alternatives, use OR in capital letters. For example, search for "new zealand kayaking OR biking." Word Order To search for an exact phrase,, just put quotation marks around two or more words. For example, search on "to be or not to be" (typing the quotation marks into the box).

9 Search and advanced Search features (continued) The AND command is used in order to require that all search terms be present on the Web pages listed in result. The NOT command is used in order to require that a particular search NOT be present on Web pages listed in result. The NEAR command is used to specify how close terms should appear to each other. Example: moon NEAR river. The Nesting () allows you to build complex queries. You nest queries using parentheses, like this: impeachment AND (clinton OR johnson)
