Have a page with Search portlet.
Search for tags or words contained in Web Contents.

The results are displayed but with title "Web Content (0)" and at the end "Showing 0 results".

It happens everytime I search for tags, and sometimes when I search for some words contained in a searchable field of a Web Content.

Note: my Web Contents use custom structures.
