searching for tickets

Hi devs, Previously, I could effectively use Google as a way to search for contents in tickets, with a query like

site:ghc.haskell.org/blah/blah/tickets http://ghc.haskell.org/blah/blah/tickets type families

(I can't remember the exact URL, and Trac has been taken down so I can't figure it out.) Now, though, when I search for

site:gitlab.haskell.org/ghc/ghc/issues/ http://gitlab.haskell.org/ghc/ghc/issues/ type families

I get nothing. Is there something in our setup that stops Google from indexing our issues? Or has Google just missed the memo about the issues page being opened up? Thanks! Richard
