I believe there was a way to search in two categories (at least someone told me), but I've never been able to find it unfortunatly. What you could do as an alternative is use google: if you type [ "Duet original songs" + "GUMI original songs" site:vocaloidlyrics.fandom.com ] the search results should give songs in both the duet category and the GUMI category. This might still give some songs that are for example GUMI solo songs with an alternative duet version, but most of the non-relevant songs should be filtered out. If you want to filter everything else out [ "Duet original songs" + "GUMI original songs" + "GUMI and" OR "and GUMI" site:vocaloidlyrics.fandom.com ] will probably work. I'm sorry I can't be of more help orz.
