PreFilterShardSize(long?)

Defines a threshold that enforces a pre-filter roundtrip to prefilter search shards based on query rewriting if the number of shards the search request expands to exceeds the threshold. This filter roundtrip can limit the number of shards significantly if for instance a shard can not match any documents based on its rewrite method i.e., if date filters are mandatory to match but the shard bounds and the query are disjoint.

Declaration
public MultiSearchDescriptor PreFilterShardSize(long? prefiltershardsize)
Parameters
Type Name Description
long? prefiltershardsize
Returns
Type Description
MultiSearchDescriptor
