Class DeleteByQueryRequest

All Implemented Interfaces:
IndicesRequest, IndicesRequest.Replaceable, Writeable, RefCounted, TaskAwareRequest, ToXContent, ToXContentObject

Creates a new DeleteByQueryRequest that uses scrolling and bulk requests to delete all documents matching the query. This can have performance as well as visibility implications. Delete-by-query now has the following semantics:
  • it's non-atomic, a delete-by-query may fail at any time while some documents matching the query have already been deleted
  • it's syntactic sugar, a delete-by-query is equivalent to a scroll search and corresponding bulk-deletes by ID
  • it's executed on a point-in-time snapshot, a delete-by-query will only delete the documents that are visible at the point in time the delete-by-query was started, equivalent to the scroll API
  • it's consistent, a delete-by-query will yield consistent results across all replicas of a shard
  • it's forward-compatible, a delete-by-query will only send IDs to the shards as deletes such that no queries are stored in the transaction logs that might not be supported in the future.
  • it's results won't be visible until the index is refreshed.
