Delete By Query APIedit

The delete by query API will be removed in 2.0: it is problematic since it silently forces a refresh which can quickly cause OutOfMemoryError during concurrent indexing, and can also cause primary and replica to become inconsistent. Instead, use the scroll/scan API to find all matching ids and then issue a bulk request to delete them.

The delete by query API allows one to delete documents from one or more indices and one or more types based on a query. Here is an example:

import static org.elasticsearch.index.query.FilterBuilders.*;
import static org.elasticsearch.index.query.QueryBuilders.*;

DeleteByQueryResponse response = client.prepareDeleteByQuery("test")
        .setQuery(termQuery("_type", "type1"))
        .execute()
        .actionGet();
