Exact Nearest Neighbor Vector Search Now Supported

Hello! I’m excited to announce that exact nearest neighbor search is now supported in Atlas Vector Search.

Instead of specifying numCandidates in your $vectorSearch queries, specify exact: True and your queries will be guaranteed to return the closest results. This may be helpful for workloads with fewer than 10k vectors, multi-tenant workloads with fewer than 10k vectors per tenant, and benchmarking the recall of your approximate nearest neighbor vector search queries.
