[facets] Correctly look for inputs of type "hidden" (closes #4502768) jQuery ':hidden' selector looks at CSS visual properties (eg, 'display', 'visibility'). The intent here was probably to look for inputs of type "hidden", which many facets use to store user selection data (eg, FacetRangeWidget). The problem is that regular text inputs (eg the "has_text" facet which has a '<input type="text"/>') will be picked up by this selector if they are inside a folded facet. Chaos and destruction ensue.

You can as well type complex queries using the RQL_ query language, 
used every where to build dynamic pages of this site.

You can use one of the following prefixes to specify which kind of search you
want:
