Multiple tags search pagination issue

[ghost]

If I do a search with multiple tags the pagination is broken.

I see that in phpmyfaq/inc/PMF/Faq.php on line 506 there is a filterInput() function with 'FILTER_VALIDATE_INT' parameter but the URL of a search with multiple tags is something like phpmyfaq/?action=search&tagging_id=1,2.

I solved passing 'FILTER_DEFAULT' as the third parameters of filterInput() function that check only strings
