This plugin adding autocomplete functionality to search input field. It is using core jQuery library as well as 
autocomplete jquery plugin from http://www.pengoworks.com/workshop/jquery/autocomplete.htm
This plugin requires zero configuration, but since version 1.2.0 there is admin screen where you can enable the extra ‘number of matches’ next to each option and other goodies. 
You just need to activate and it’s ready to be used in the blog. The plugin is tested with WordPress 2.6.5, but until there aren’t big core changes, it sould work for all future releases. I don’t have 
information if this plugin will work with older versions of WordPress, but for sure it is working with 2.6.x. The last version 1.2.0 is tested on WP 2.7.1.
New in 1.3.5: When it’s selected to display posts and/or pages and the autosubmit is ON, then when the user clicks on the selected row it will go directly to the post or page url. This way user are skipping one step. The change affect only pages and posts. Categories and tags behave as now.
New in 1.3.0: Added result type option in admin. From now on you can choose which type of results will be displayed.
New in 1.2: This version could display number of matches found in the blog.
New in 1.2.1: Small fix for table prefixes and adding autosubmit once the item from the list is selected.
