How to construct QueryBuilder from JSON DSL when using Java API in ElasticSearch?
You can use setQuery, which can receive a json format string.
/** * Constructs a new search source builder with a raw search query. */public SearchRequestBuilder setQuery(String query) { sourceBuilder().query(query); return this;}Note this: only part of the DSL is needed, the {"query": } part is omitted, like this:
SearchResponse searchResponse = client.prepareSearch(indices).setQuery("{\"term\": {\"id\": 1}}").execute().actionGet();
It might be worth investigating low level rest client. With this you can do:
RestClient esClient = RestClient.builder(new HttpHost("localhost", 9200, "http")).build();Request request = new Request("POST", "/INDEX_NAME/_doc/_search");request.setJsonEntity(yourJsonQueryString);Response response = esClient.performRequest(request);String jsonResponse = EntityUtils.toString(response.getEntity());
