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;

Returns
Type Description
double

The fractionLeafNodesToSearchOverride.

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;

Returns
Type Description
int

The neighborCount.
