Class StructuredQuery.FindNearest (3.30.2)

public static final class StructuredQuery.FindNearest extends GeneratedMessageV3 implements StructuredQuery.FindNearestOrBuilder

Nearest Neighbors search config. The ordering provided by FindNearest supersedes the order_by stage. If multiple documents have the same vector distance, the returned document order is not guaranteed to be stable between queries.
