advanced way to search games on dolphin wiki ?

[dr.mario]

what i want is to search all games that are:

multiplayer & use the classic controller

but from the wiki website, i can only click and view a list of multiplayer games, or click and view a list of games that use the classic controller. obviously to find one from the other would waste alot of time, considering there *must* be a way to simply search both at once, on mediawiki sites.

is there a way to do an advanced search on wiki.dolphin-emu.org ?

on mediawiki, i found this:

Quote:Using MediaWiki search to find category intersections
As of April 2008 it is possible to use the Search tool to find category intersections; however, this facility does not look inside subcategories. To find a category intersection, type incategory:"CategoryName" in the search box for each category of interest. For example, incategory:"German films" incategory:"1998 films" will return the articles that are common to both categories – German films released in 1998. This method will only work for categories which have been directly entered into articles (e.g. Category:1998 films), not where categories are assigned through templates, e.g. from any of the stub message templates or from the template {{Infobox film}}.

however, using dolphin's search box, the above doesn't work !!!

also i found these extensions search results:
