Search not working correctly

I do not get any hits when searching for "top box", "top", or "box". The quotes.are not used in the search argument. When I search for "givi", I get a lot of hits with the words "top box" within the posts.
Just looking for a locking top box that can easily be removed and hold my modular helmet, vest, and gloves. At least 45 litres.

Try 'top case'; I got 385 hits.

Thanks Mike!
