Update and Delete by Query

Note

REST endpoints: _update_by_query and _delete_by_query.

POST /user_info/_update_by_query?refresh=true {"query":{"term":{"uid": ?}},"script":{"source":"ctx._source.name = params.name","params":{"name": ?}}}
POST /user_info/_delete_by_query?refresh=true {"query":{"term":{"uid": ?}}}

Bind uid followed by the new name for the update, and uid for the delete. All matching documents are processed; matching business fields do not imply identical document _id values.

Partial Success

Writes by query may encounter version conflicts or partially succeed. Completed changes are not rolled back automatically. The returned count is not a full task report; asynchronous task options do not make the driver wait for task completion.
