58944 Auto-Suggest Search Form

I require script that can take a text file of search queries, and suggest a list of queries to the user, based on what has been input into the search form (searchbox). Some examples of this are: [login to view URL] or [login to view URL] The queries in the text file are each on a new line. e.g. Test Search Test Search If the user starts to type tes.... the script should suggest (a href="/search?q=test+search")Test Search(/a) ...in a floating HTML element or something similar. There should also be a function to allow me to limit the amount of suggestions given. Then code has to be secure and will be extensively tested to confirm.
