  • If you want to pass a JSON DSL query, you're better off using the [low-level REST client](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-low-usage-requests.html). Using the high-level REST client requires you to build the query using [the Java DSL](https://www.elastic.co/guide/en/elasticsearch/client/java-rest/current/java-rest-high-search.html). – Val Sep 25 '19 at 11:22
  • is this okay to use low-level Rest client?? – tisispa1 Sep 25 '19 at 11:56
  • Of course it is. Even the Apache HTTP client is OK. It only depends on your use case and how you want to interact with ES. – Val Sep 25 '19 at 11:57
  • @Val okay!! I have another qus if suppose am using Apache ES protected with credentials how come I will pass the username , pwd through Apache?? – tisispa1 Sep 25 '19 at 12:01

    As described in the [Apache client official documentation](https://hc.apache.org/httpcomponents-client-ga/tutorial/html/authentication.html) :-) – Val Sep 25 '19 at 12:06
  • yeah got it..!! And in `rest high level client` we can construct the search request and pass the JSON DSL Query right?? – tisispa1 Sep 25 '19 at 12:11
  • In the high level REST client, you can b64 encode your raw JSON query and pass it in a [wrapper query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-wrapper-query.html) – Val Sep 25 '19 at 12:13
  • @Val ```NamedXContentRegistry``` we can pass a json raw query AND ```XContentParser``` it will parse the raw query correct me if am wrong...? – tisispa1 Sep 25 '19 at 12:21
  • Can you show your query? – Val Sep 25 '19 at 12:24
  • @Val check this – tisispa1 Sep 25 '19 at 12:33
