I'm looking for Wordpress plugin that just improved the search results, but doesn't add the the search box.
At the moment wordpress isn't even doing plurals. So does anyone know a good plugin that will make the search a whole lot better?
Try using below plugins...
Use Relevanssi Plugin for Multilingual Support http://wordpress.org/extend/plugins/relevanssi/
Use WPSearch for well behave custom Search http://wordpress.org/extend/plugins/wpsearch/
Use Search-Everything for all type of Content Search http://wordpress.org/extend/plugins/search-everything/
