They made it sound more serious, as if 2 archives from the torrent file itself was corrupted for some reason, but I don't know, I'll leave them a message on their own feedback page to maybe clarify or ask.

There's another indexer that's not published just yet but coming soon, https://anifix.org It's kind of taking a different approach to indexing anime to some extent.

There's some corrupt data in the DB here due to bugs, server crashes etc. I did consider cleaning those up before releasing the dump, but I never got around to it unfortunately.
There shouldn't be many of these instances and the vast majority of data should be fine.

As for searching, I believe their implementation is different to what I have here, so differences don't sound surprising. If their search doesn't list an entry that you think should be present, I'd suggest notifying them of the discrepancy so that they can look into it.

Hey admin, I still use AT for old releases so I hoped it'd stay around for longer, not sure how common this is, anyway, did you look at .xyz news, they're saying:
"Unfortunately, some files are missing and are probably gone forever. Two of the archives included in the animetosho.org dumps were corrupted, so there is nothing we can recover from those parts."
I've noticed a few random releases appear in your search but not theirs.
