drun shows inexplicable search hits

[fenugrec]

I'm trying to understand where drun finds some of the hits it reports. Example : rofi -show drun , I type in "suse" , and I get a hit for "libreoffice". What ?

Eh, -drun-match-fields by default includes 'categories', and I see now how this can cause some surprising string matches (the one above was for libreoffice-startcenter.desktop:Categories=Office;X-Red-Hat-Base;X-SuSE-Core-Office; ).
