Issue filtering results in search results pages from the second page on

To reproduce:

• On a clean wiki search for a word (e.g. xwiki)
• Go to the second page of the search results page
• Refine your search by choosing one of the filters on the right. For the scope of this test I filtered the results by checking blog in the "Space" category.

Result:

• After the filtering I see " Results 1 - 5 of 5 " written, but no actual results (see the attached image). It seems results are properly displayed only if you apply a filter when you're located in the first results page.
