org.elasticsearch.search.internal.ShardSearchLocalRequest

All Implemented Interfaces:

HasContext, HasContextAndHeaders, HasHeaders, ShardSearchRequest

public class ShardSearchLocalRequest
extends ContextAndHeaderHolder
implements ShardSearchRequest

Shard level search request that gets created and consumed on the local node. Used by warmers and by api that need to create a search context within their execution. Source structure:

 {
  from : 0, size : 20, (optional, can be set on the request)
  sort : { "name.first" : {}, "name.last" : { reverse : true } }
  fields : [ "name.first", "name.last" ]
  query : { ... }
  facets : {
      "facet1" : {
          query : { ... }
      }
  }
 }

Description copied from interface: ShardSearchRequest

This setting is internal and will be enabled when at least one node is on versions 1.0.x and 1.1.x to enable scrolling that those versions support.

Specified by:

useSlowScroll in interface ShardSearchRequest

Returns:

Whether the scrolling should use regular search and incrementing the from on each round, which can bring down nodes due to the big priority queues being generated to accommodate from + size hits for sorting.
