Some significant bugs seem to have been introduced during the migration; most notably, it no longer appears to be possible to exclude multiple authors (and, as another commenter pointed out, the author names themselves are not being properly matched either). Both of these completely break our analytics in a way that doesn't seem to be practical to work-around (we'd need to retrieve hundreds of extra pages in some instances). For example, author=!AutoModerator,!SomeOtherBot would previously exclude both those accounts, but now it doesn't exclude either of them. If I'm reading the metadata correctly, this is because it's matching "any" of these conditions, which of course doesn't make sense when trying to exclude things.

Additionally, are the unique, before_id/after_id, and distinguished parameters functional, are there examples of how these are supposed to be used? They have never worked for me at all even before the migration, though it is possible I am just using them wrong (or even that the documentation is wrong or unclear).

Finally, is metadata=false not the correct way to turn off metadata? It seems to be on by default now, and it seems wasteful to be returning this in cases we aren't going to be using it.

Edited to add: It seems the url parameter does not work anymore either.
