In AUR 4 categories were removed and we can now attach arbitrary "keywords" to packages. It is not clear what the exact purpose is though. If keywords really should be "better categories" (or tags) then the current implementation does't do that. Keywords are just more words that are searched with a "normal" search. No distinction is made if a keyword given in a search matches the package name, the description or is an actual "keyword" of a package. You also can't filter search results like you used to be with categories . So what works ATM is having keywords as a better place to put "search hints". Well, I like free-form tags/categories better, but if they should be search hints, then this should be documented somewhere. Anyways, I opened an issue about that: https://bugs.archlinux.org/task/45447 but as a second thought it would be nice to know what the community thinks about this. -- JonnyJD
