ADD - 'superspecial' search modification for !empty using the new union bit_or technique. 
This allows an !empty[fieldref] or !empty[fieldname] search to be combined with other special searches such as for !collection search refinement. 

Also modify search titles to show case of resource types properly (ex. All ICC was displaying as All Icc)
