Question: I'm looking for a JQuery plugin that will assist in an incremental search e.g. - the user starts typing into a textbox and an AJAX call is made to dynamically get results as the user types.

Answer: 
Something like [this plugin](http://www.pengoworks.com/workshop/jquery/autocomplete.htm) maybe.
Just googled - [Autocomplete](http://www.devbridge.com/projects/autocomplete/jquery/).
