Early look at k_NN pre filtering?

Hi all,

Just wondering if it’s possible to get a look at the development of the k-NN pre-filtering feature: https://github.com/opensearch-project/k-NN/issues/376

For example, any pre-release code or other resources?

Would love to get a chance to test out this feature, even if it’s not quite ready for production use.

Hi Pandu,

We’re working on the feature at the moment, the plan is to finish few things and share POC code as part of the corresponding RFC regarding the filtering support.

Once RFC has been published we’ll post an update in this thread.
