Search with Keyword not working

When I try to search an item with keyword it returns me nothing(Your query returned no resul), but when I search with Boolean or exact match it returns to me the items that I want. Any idea what might be the cause?

I'm using Omeka 2.3, inside XAMPP insdide windows 7.

Is the keyword you are searching something which appears frequently in your site?

At the moment i am just doing some test, and I have only 1 item in the database, is this the same cause that you referred to the link?

Do you still have the problem if you add a few more items?

That's seems to be the key. If I add more than 2 items it works, now I can search even with keyword.

Thx mebrett :)
