I've also noticed Google having indexing issues over the past ~year:
Some popular models on Hugging Face never appear in the results, but the sub-pages (discussion, files, quants, etc.) do.
Some Reddit pages show up only in their auto-translated form, and in a language Google has no reason to think I speak. (Maybe there's some deduplication to keep machine translations out of the results, but it's misfiring and discarding the original instead?)
