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.
However, note also that web pages may change URLs or disappear completely. If you continue to have trouble finding a site, try searching by keywords that adequately describe the site. Be critical and evaluate the information you find on the Internet. The fact that the information appears on the Internet does not mean that it is correct or accurate. To access Web sites from another country or in a different language, enter your search keywords in that language and try using a search engine from that country.
