I have repo: https://copr.fedorainfracloud.org/coprs/rpmsoftwaremanagement/rpm-gitoverlay-1464195992.3972952/
But search by name doesn't work: https://copr.fedorainfracloud.org/coprs/fulltext/?fulltext=rpm-gitoverlay-1464195992.3972952
it returns "no projects". Not sure if it's frontend or backend bug.
We are using the following regular expression to match searchable parts of a copr name: r"\w+(-\.?\w+)*"
This expression will match everything before dot of the name "rpm-gitoverlay-1464195992.3972952" and puts this part into the search index (so search for just "rpm-gitoverlay-1464195992" works).
Let's keep it like this unless more problems arise. I think most people will search for just rpm-gitoverlay.
