Special:LinkSearch does not display results for protocol relative URLs

compare

the last one actually displays protocol relative URLs instead of https, which
might be another bug to open, I guess.

The fact that the https search finds protocol-relative URLs is not a bug. The fact that the protocol-relative search doesn't work, however, is a bug.

Then I would assume that

or at least

http://cs.wikipedia.org/wiki/Speci%C3%A1ln%C3%AD:Hled%C3%A1n%C3%AD_odkaz%C5%AF/http://commons.wikimedia.org

will find the protocol relative URLs as well which it doesn't.

The externallinks table contains to rows for a protocol relative link, so you can find it with https and http in your search request. Maybe they need three rows?

See bug 29854

With gerrit change 28908 merged some time ago, some bugs were fixed. Does the current situation solve this bug?

No.

Is this duplicated by (or could be usefully merged from) T14810: Special:Linksearch should default to all protocols (protocol-less column for externallinks) ?
