Does mongo-java-driver support ENN search?

I have seen examples with ENN search on documentation and mongo-java-driver has no interface on vectorSearch that omits numCandidates?

I wonder if mongo-java-driver support ENN search or just ANN only for now.

Hi @Xiang_Li! We do not currently support this feature in the Java driver, but are working on adding it and should have it available soon.
