Forgive me, I'm new to wiki and kinda clueless. I want to search for articles that have multiple categories. For example, if I want to find all GUMI original songs that are duets, that's two categories, duets and GUMI songs. But I wouldn't want to sift through endless information irrevelant to me. Like, if I search through all the duet songs, there's gonna be a lot of songs without GUMI in them, and if I search through all the GUMI songs, there's gonna be a lot of songs that aren't duets. How do I search specifically for an article that is in multiple categories?

Sorry if this makes no sense, I didn't really know how to phrase it.
