public class DeleteByQueryRequest
extends AbstractBulkByScrollRequest<DeleteByQueryRequest>
implements IndicesRequest.Replaceable

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.

Method Detail

self

protected DeleteByQueryRequest self()

Description copied from class: AbstractBulkByScrollRequest

`this` cast to Self. Used for building fluent methods without cast warnings.

Specified by:

self in class AbstractBulkByScrollRequest<DeleteByQueryRequest>

validate

public ActionRequestValidationException validate()

Overrides:

validate in class AbstractBulkByScrollRequest<DeleteByQueryRequest>

forSlice

public DeleteByQueryRequest forSlice(TaskId slicingTask,
                                     SearchRequest slice,
                                     int totalSlices)

Description copied from class: AbstractBulkByScrollRequest

Build a new request for a slice of the parent request.

Specified by:

forSlice in class AbstractBulkByScrollRequest<DeleteByQueryRequest>

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

indices

public IndicesRequest indices(java.lang.String... indices)

Description copied from interface: IndicesRequest.Replaceable

Sets the indices that the action relates to.

Specified by:

indices in interface IndicesRequest.Replaceable

indices

public java.lang.String[] indices()

Description copied from interface: IndicesRequest

Returns the array of indices that the action relates to

Specified by:

indices in interface IndicesRequest

indicesOptions

public IndicesOptions indicesOptions()

Description copied from interface: IndicesRequest

Returns the indices options used to resolve indices. They tell for instance whether a single index is accepted, whether an empty array will be converted to _all, and how wildcards will be expanded if needed.

Specified by:

indicesOptions in interface IndicesRequest
