Press Enter or Return. The search returns a list of hyperlinks to pages that contain the text string typed into the Search text box. If you click on one of these hyperlinks and display the page, you will notice that the text string for which you searched is underlined in green everywhere it appears on the page. During the initial search, the search database is loaded into memory. This takes a few seconds.
Subsequent searchs are almost instantaneous.
Hits are returned if the strings occur within 20 words of each other. If you include multiple strings within quotes, only the exact match of those strings is returned. Spaces are included in the search. The search engine does not recognize general wildcard characters.
