I tried to report this problem, but there is no proper form for this case, it would be inconsistent. If anyone finds a better place to tell someone about this, please do.
To the problem, that happened just a few minutes ago, you should be able to reproduce it right now.
First, I have searched for this exact string, with the shown quotes:
"trolls on the treasure island"
Strangely, it gave me no results. It is obvious that results must exist, but none were given. This is the name of a NES game! Official one. Reloaded a few times, not believing it. No change.
Then I had the "not smart at all" idea of deleting the quotes, but obvious this should imply in garbage results I was not interested in. But the search was, exactly:
trolls on the treasure island
What is the surprise? The results are exactly
what everyone expected for the first search! The perfect results exist, and were shown. For harder queries I would have tried a bang for another search engine, and all of them would bring results (I won't even check this).
I have made print-screens of both results:
