This search tool is designed to help the visitor's to your site, search for words which have been indexed from your site. If follows the same basic idea as the Google Suggest search. As the user begins to type in the search box, an ajax (asynchronous javascript) request is made back to our server, querying the words in your index that begin with the letters the user had typed. Almost immediately, a list of suggestions are returned to the user as a list just underneath the search box. They are able to navigate this list and choose a word that they were beginning to type.

This is a powerful tool to speed up the search for a visitor to your site. As only words that appear in your index are shown to the user, they can be sure that a search on that word will match pages on your site.
