In the recent 4.7.11 update, I've noticed you updated the search filters code in \applications\core\modules\front\search\search.php to cast the variables as (int) types:

				if ( isset( \IPS\Request::i()->search_min_replies ) AND isset( $class::$commentClass ) )
				{
					$filter->minimumComments( (int) \IPS\Request::i()->search_min_replies + 1 );
					$baseUrl = $baseUrl->setQueryString( 'search_min_replies', (int) \IPS\Request::i()->search_min_replies );
					$titleConditions[] = \IPS\Member::loggedIn()->language()->addToStack( 'search_blurb_min_replies', FALSE, [ 'sprintf' => [ (int) \IPS\Request::i()->search_min_replies ] ] );
				}

Note how there are 3 values cast as (int) in the code above.

 

However, in the code for minimum reviews on line 514, the $baseUrl line wasn't updated:

				if ( isset( \IPS\Request::i()->search_min_reviews ) AND isset( $class::$reviewClass ) )
				{
					$filter->minimumReviews( (int) \IPS\Request::i()->search_min_reviews );
					$baseUrl = $baseUrl->setQueryString( 'search_min_reviews', \IPS\Request::i()->search_min_reviews );
					$titleConditions[] = \IPS\Member::loggedIn()->language()->addToStack( 'search_blurb_min_reviews', FALSE, [ 'sprintf' => [ (int) \IPS\Request::i()->search_min_reviews ] ] );
				}

For consistency, it should be:

					$baseUrl = $baseUrl->setQueryString( 'search_min_reviews', (int) \IPS\Request::i()->search_min_reviews );

Thank you for bringing this issue to our attention! I can confirm this should be further reviewed and I have logged an internal bug report for our development team to investigate and address as necessary, in a future maintenance release.
