Can we re-enable strict checking for KNN queries?

See original GitHub issue

A while back we discovered that KNN was producing non-deterministic results even on a deterministic index, and disabled strict top N hit checking for KNNVectorQuery.

We think/thought this was because the “deterministically random” source was seeded from each segment’s GUID, but we’ve since fixed this query to use a fixed random seed (42 of course).

Can we now re-enable strict checking of the top KNN hits?

It’s OK for the KNN results to change – that’s just needs a nightly regolding as long as we know/accept the source/reason for the change.

there’s also no harm in tracking relevance, if its not difficult to do. I just think we should stay “strict”
