Delete By Query API
editDelete By Query API
editThe delete by query API allows one to delete a given set of documents based on the result of a query:
BulkByScrollResponse response =
new DeleteByQueryRequestBuilder(client, DeleteByQueryAction.INSTANCE)
.filter(QueryBuilders.matchQuery("gender", "male"))
.source("persons")
.get();
long deleted = response.getDeleted();
As it can be a long running operation, if you wish to do it asynchronously, you can call execute instead of get
and provide a listener like:
new DeleteByQueryRequestBuilder(client, DeleteByQueryAction.INSTANCE)
.filter(QueryBuilders.matchQuery("gender", "male"))
.source("persons")
.execute(new ActionListener<BulkByScrollResponse>() {
@Override
public void onResponse(BulkByScrollResponse response) {
long deleted = response.getDeleted();
}
@Override
public void onFailure(Exception e) {
// Handle the exception
}
});
