However, when searching the Internet, you should use more than one search engine. Using two or three search engines can yield different results. You can find out about how an individual search engine conducts searches by clicking on the Help hyperlinks or the Search Tips hyperlinks that appear on a search engine's home page. Enter your search keywords in lowercase letters if you are not searching for a proper name. If you enter a search keyword that yields no results, try entering synonyms for the search keyword.
Most search engines support Boolean operators.
Boolean operators may help narrow your search. For example, if you are searching for information on Martin Luther, you may accidentally access information on Martin Luther King, Jr. as well. Again, not all search engines support Boolean operators. You should become familiar with the search engines you use by clicking on the Help hyperlinks or the Search Tips hyperlinks that appear on a search engine's homepage. Sites can return within hours or a few days.
