Thankyou, I believe I know what caused this regression.
I actually tried to reproduce this and haven't been able to so far, so at this point I'm not sure what's going on – is this self hosted?

Yes, its self hosted.
I guess that this issue has some relation with the limit parameter on the query string, as you can see bellow.

I have a lot of documents, so maybe search is looking only to the first 25 or other behaviour like that.
Maaaybe, but when the search term is perfectly matching the title like that it should be at the top of the list, not past the first page.
This issue has been automatically closed because there has been no response to the request for more information. With only the details that are currently in the issue, we don't have enough information to take action.
