The thing is, we have plenty of examples where systems that are not labeled as ai vastly outperform humans at searching knowledge bases.
A google-like search tool would probably be all you need for citations if 1) Google hadn’t killed accuracy in favor of ad placement and 2) the rest of the world hadn’t poisoned the dataset in hopes of getting picked up by Google as a first page result.
Now the hard problem isn’t to search so much as to curate an un-polluted dataset.
