often i know the exact (source) package name and want to get an overview what is where. In Debian i'd use rmadion on pureos i use https://software.pureos.net which works nicely most of the time but for very generic names i get lots of matches. If i could search for an exact package name that would help a lot already so that;
https://software.pureos.net/search_pkg?term=uuu&exact=1
would only return results for packages named `uuu` not `libuuu` or `uuufoo`.
