When trying to find a group (specifically for m+) it's somewhat annoying having to always type f.ex. "15-15" to find level 15 keys of those instances you need/have filtered. It is also annoying that f.ex. you have missing Floodgate 15 but you want to also see some of the easier 16 keys you might get invited to.

My proposed solution is to allow us to use something like "and "15-15"" as an argument f.ex. - 15-15 being fed into the search box automatically. Or even better if we could look for keys like "FLOOD("15-15") or ML("16-16")"

Requested many times and would love to do that, but not possible because addons are blocked from reading or changing the search term and also from reading the group title and comment. So there is no way to know the key level as an addon. Also see first FAQ entry.
