After activating the AdvancedSearch extension, I cannot search by categories as advertised.
For example, searching the wiki poserdazfreebies for the word "Outfit" returns many pages with the word Outfit in the title, including the page "Genesis Babydoll Outfit" that has Category:Genesis. Searching for the word "Outfit" and the category "Genesis" returns "Create the page "Outfit deepcat:genesis" on this wiki! There were no results matching the query."
Some web searching indicates that this functionality requires something called CirrusSearch to be enabled in order to work correctly, but I didn't see that on the Extensions list.
Please fix this.
