How to planning HNSW index ef, efConstruction and maxConnections parameters with PQ?

Hi @DevelMyCry !!

First, any specific reason to use 1.26.0?

The latest one from this branch is 1.26.13, and those 13 releases are the ones that bring all patches we backported from 1.28

Of course, 1.28 will probably get you even better results. For example, you may try using ACORN, that can help on specific queries.

By the way, not sure if you saw this article in our academy:

there is some interesting information there.

Thanks!
