often i know the exact (source) package name and want to get an overview what is where. In Debian i'd use rmadison 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.
