clearFractionLeafNodesToSearchOverride()

public FindNeighborsRequest.Query.Builder clearFractionLeafNodesToSearchOverride()

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.
