I am searching for Wordpress wordpress plugin that simply enhanced the search engine results, but does not add the the search box.

Right now wordpress is not even doing plurals. The same is true anybody know a great wordpress plugin that can make the search a great deal better?

http://wordpress.org/extend/plugins/relevanssi/ does full text, fuzzy match, partial match and supports quotes and category searches. It renews its index after each publish/page is added.

Try this.
