At least for issues, their search got a lot worse recently - it doesn't do substring search in the same way (or maybe at all - I haven't checked in detail), so you can't search for non-initial words in compound-words. This makes searching through German issues an exercise in frustration... .
Agreed, it's really bad.
I think they really improved the code/repository search, but finding issues got really worse.
And IMO finding issues easily should be a top priority for a platform like GitHub.
The old search was much better than the new search. The new search can never find exact strings in my repos, even when I have copy-pasted those strings from my repo to the search bar!
It got a lot better. That’s kind of the point behind it being behind a login wall now.
What? I think it is one of the strengths of GitHub compared to other platforms.
