Optional. The number of neighbors to find via approximate search before exact reordering is performed; if set, this value must be > neighbor_count.

int32 approximate_neighbor_candidates = 1 [(.google.api.field_behavior) = OPTIONAL];

Optional. 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.

double leaf_nodes_search_fraction = 2 [(.google.api.field_behavior) = OPTIONAL];
