      • hasDatapoint

        public boolean hasDatapoint()
         Required. The datapoint/vector whose nearest neighbors should be searched
 for.

      • getNeighborCount

        public int getNeighborCount()
         The number of nearest neighbors to be retrieved from database for each
 query. If not set, will use the default from the service configuration
 (https://cloud.google.com/vertex-ai/docs/matching-engine/configuring-indexes#nearest-neighbor-search-config).
        int32 neighbor_count = 2;

      • getPerCrowdingAttributeNeighborCount

        public int getPerCrowdingAttributeNeighborCount()
         Crowding is a constraint on a neighbor list produced by nearest neighbor
 search requiring that no more than some value k' of the k neighbors
 returned have the same value of crowding_attribute.
 It's used for improving result diversity.
 This field is the maximum number of matches with the same crowding tag.
        int32 per_crowding_attribute_neighbor_count = 3;
        Specified by:
        getPerCrowdingAttributeNeighborCount in interface FindNeighborsRequest.QueryOrBuilder
        Returns:
        The perCrowdingAttributeNeighborCount.

      • getApproximateNeighborCount

        public int getApproximateNeighborCount()
         The number of neighbors to find via approximate search before
 exact reordering is performed. If not set, the default value from scam
 config is used; if set, this value must be > 0.
        int32 approximate_neighbor_count = 4;
        Specified by:
        getApproximateNeighborCount in interface FindNeighborsRequest.QueryOrBuilder
        Returns:
        The approximateNeighborCount.

      • getFractionLeafNodesToSearchOverride

        public double getFractionLeafNodesToSearchOverride()
         The fraction of the number of leaves to search, set at query time allows
 user to tune search performance. This value increase result in both
 search accuracy and latency increase. The value should be between 0.0
 and 1.0. If not set or set to 0.0, query uses the default value specified
 in
 NearestNeighborSearchConfig.TreeAHConfig.fraction_leaf_nodes_to_search.
        double fraction_leaf_nodes_to_search_override = 5;
        Specified by:
        getFractionLeafNodesToSearchOverride in interface FindNeighborsRequest.QueryOrBuilder
        Returns:
        The fractionLeafNodesToSearchOverride.
