Delete ElasticSearch by Query with JEST

Question

I have some custom data(let's call Camera) in my ElasticSearch, the data showed in Kibana is like

And I tried to delete data by Query according to the accepted answer in this article ElasticSearch Delete by Query, my code is like

String query = "{\"Name\":\"test Added into Es\"}";
DeleteByQuery delete = new DeleteByQuery.Builder(query).addIndex(this._IndexName).addType(this._TypeName).build();

JestResult deleteResult = this._JestClient.execute(delete);

And the result is 404 Not Found.

Its obvious that there exist one Camera data in ElasticSearch which Name match the query, so I believe the 404 is caused by other reason.

Did I do anything wrong? Should I change the query string?

The query needs to be a real query, not a partial document

Try with this instead

String query = "{\"query\": { \"match\": {\"Name\":\"test Added into Es\"}}}";

Can you share the full error please? and also which version of ES you're using

Sure! The full content is this

{"found":false,"_index":"cameras","_type":"camera","_id":"_query","_version":1,"result":"not_found","_shards":{"total":2,"successful":1,"failed":0}}

. And I'm using ElasticSearch 5.4.0.

Ok I see the problem. Jest uses the _query endpoint which was the endpoint used by the Delete by query plugin back in ES 2.x. From ES 5 onwards, the delete by query feature has made it into the core and the endpoint is now named _delete_by_query. That change has been made recently in Jest and will soon be released

So you have a few options: 1) downgrade to ES 2.4, 2) wait until the new Jest gets released or 3) checkout the Jest master branch and build it yourself.

Sorry for responding so lately... I didn't search afterwards, because building it by myself is quite impossible for me to achieve, and also I transfer my work on another part, so I didn't work on this issue anymore. But still very appreciate for your information and suggestions, hope there would be a way to solve(hopefully provided by JEST) afterwards. Thanks!
