Elastic Search High Level Java Client UpdateByQueryRequest API help required

Question

I am migrating from normal ES Http calls to ES HighLevelJavaClient.

I want to convert this old implementation POST /_update_by_query

 {
  "script": {
    "inline": "ctx._source.collibra_match_for = []"
  },
  "query": {
    "bool": {
      "filter": {
        "script": {
          "script": {
            "source": "doc['collibra_match_for.keyword'].values.length > 0",
            "lang": "painless"
          }
        }
      }
    }
  }
}

To High Level client code.

The code I tried is :

  UpdateByQueryRequest request = new UpdateByQueryRequest();
    request.setConflicts("proceed");
    request.setQuery(QueryBuilders.boolQuery().filter(QueryBuilders.scriptQuery(new Script("doc['collibra_match_for.keyword'].values.length > 0"))));
    request.setScript(new Script(ScriptType.INLINE, "painless","ctx._source.collibra_match_for = []",Collections.emptyMap()));
    request.setRefresh(true);
    try {
        BulkByScrollResponse bulkResponse = esClient.updateByQuery(request, RequestOptions.DEFAULT);
        long totalDocs = bulkResponse.getTotal();
    } catch (IOException e) {
        e.printStackTrace();
    }
}

But I am getting this error :

Elasticsearch exception [type=exception, reason=Incorrect HTTP method for uri [/_update_by_query?requests_per_second=-1&ignore_unavailable=false&expand_wildcards=open&allow_no_indices=true&refresh=true&conflicts=proceed&timeout=1m] and method [POST], allowed: [DELETE, PUT, GET, HEAD]]

Any help will be appreciated :)

Answer 1

I actually found the answer to this question.. We just need to add the index name in the constructor. This is the final answer to the question.Hope it will be useful to someone in future :)

    UpdateByQueryRequest request = new UpdateByQueryRequest(INDEX_NAME);
    request.setConflicts("proceed");
    request.setQuery(QueryBuilders.boolQuery().filter(QueryBuilders.scriptQuery(new Script("doc['collibra_match_for.keyword'].values.length > 0"))));
    request.setScript(new Script(ScriptType.INLINE, "painless","ctx._source.collibra_match_for = []",Collections.emptyMap()));
    request.setRefresh(true);
    try {
        BulkByScrollResponse bulkResponse = esClient.updateByQuery(request, RequestOptions.DEFAULT);
        long totalDocs = bulkResponse.getTotal();
    } catch (IOException e) {
        e.printStackTrace();
    }
