Just in case anyone else is looking to try this plugin, I think it may be too out of date now. Error on activation:

Deprecated: __autoload() is deprecated, use spl_autoload_register() instead in C:\xampp\htdocs\dwdfrontendplugins\wp-content\plugins\typeahead\typeahead.php on line 42

Notice: register_uninstall_hook was called incorrectly. Only a static class method or function can be used in an uninstall hook. Please see Debugging in WordPress for more information. (This message was added in version 3.1.0.) in C:\xampp\htdocs\dwdfrontendplugins\wp-includes\functions.php on line 5229
