Hello folks, i need some help please , to write a correct Search Query to match all things inside my Index in Elasticsearch . I want also to translate this Query in Java Low Level Rest Client API. ```auto GET try1/_search { "query": { "match_all": {} } } ``` I tried something like this bellow , and it gives me nothing from the Index. I do now know where to put my Index name to search bellow, ```auto SearchRequestBuilder sr = new SearchRequestBuilder(client, SearchAction.INSTANCE) .setSearchType(SearchType.DFS_QUERY_THEN_FETCH) .setQuery(QueryBuilders.matchAllQuery()); ``` the Code above returns me this , ```auto {"query":{"match_all":{"boost":1.0}}} ``` I tried this too , and did not work, bellow , ```auto SearchRequest searchRequest = new SearchRequest("try1"); SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder(); searchSourceBuilder.query(QueryBuilders.matchAllQuery()); searchRequest.source(searchSourceBuilder); ``` the Result is , ```auto {searchType=QUERY_THEN_FETCH, indices=[try1], indicesOptions=IndicesOptions[id=38, ignore_unavailable=false, allow_no_indices=true, expand_wildcards_open=true, expand_wildcards_closed=false, allow_aliases_to_multiple_indices=true, forbid_closed_indices=true, ignore_aliases=false], types=[], routing='null', preference='null', requestCache=null, scroll=null, maxConcurrentShardRequests=0, batchedReduceSize=512, preFilterShardSize=128, allowPartialSearchResults=null, source={"query":{"match_all":{"boost":1.0}}}} ``` Can Anybody please help me to write the Search Query to match\_all in the right way using Low Level Client Rest API ??? thx. ---

Are you sure you want to use the low level client and not the high level one? ---

yes i want to give the Low Level Client a try , i use actually the **TransportClient** , to Creat Index and send Data to Elasticsearch , is there any Option , to use my TransportClient in order to write the Match\_all Search Query in a right Way??? **I am not using** the RestClient , is there any different between both???? I Used the High Level Client too like this bellow , and still even did not give me the Content of the Index , ```auto try (RestHighLevelClient client = new RestHighLevelClient( RestClient.builder(HttpHost.create("http://localhost:9200")))) { SearchRequest searchRequest = new SearchRequest("try1"); SearchSourceBuilder searchSourceBuilder = new SearchSourceBuilder(); searchSourceBuilder.query(QueryBuilders.matchAllQuery()); searchRequest.source(searchSourceBuilder); System.out.println("searchrequest is : " + searchRequest); } ``` The Result of this High Level Client Query is , ```auto {searchType=QUERY_THEN_FETCH, indices=[try1], indicesOptions=IndicesOptions[id=38, ignore_unavailable=false, allow_no_indices=true, expand_wildcards_open=true, expand_wildcards_closed=false, allow_aliases_to_multiple_indices=true, forbid_closed_indices=true, ignore_aliases=false], types=[], routing='null', preference='null', requestCache=null, scroll=null, maxConcurrentShardRequests=0, batchedReduceSize=512, preFilterShardSize=128, allowPartialSearchResults=null, source={"query":{"match_all":{"boost":1.0}}}} ``` Nothing seems to work correctly . Cause i need the Content of the Index under "\_source". Any Suggestion i will be thankfull. ---

I tried again with the RestClient API insead of TransportClient like bellow, ```auto RestClient restClient = RestClient.builder( new HttpHost("localhost", 9200, "http")).build(); RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http")); Response response1 = restClient.performRequest("GET","try1");//here the IndexName RequestLine requestLine = response1.getRequestLine(); HttpHost host = response1.getHost(); int statusCode = response1.getStatusLine().getStatusCode(); //org.apache.http.Header[] headers = response1.getHeaders(); String responseBody = EntityUtils.toString( response1.getEntity()); System.out.println("result is : " + responseBody); ``` The Result seems to be better, cause it returns the Typs of all Fields of my Index , like bellow , ```auto {"try1":{"aliases":{},"mappings":{"_doc":{"properties":{"my_id":{"type":"text","fields":{"keyword":{"type":"keyword","ignore_above":256}}},"field":{"type":"text","fields":{"keyword":{"type":"keyword","ignore_above":256}}},"gender":{"type":"text","fields":{"keyword":{"type":"keyword","ignore_above":256}}}}}},"settings":{"index":{"creation_date":"1561710794108","number_of_shards":"5","number_of_replicas":"1","uuid":"IWI-z1wPRXiUt3N3RINEYw","version":{"created":"6030199"},"provided_name":"try1"}}}} ``` I just need the Values inseatd of the Typs of Fields . Is there any Option to do that ?? thx ---

So i have resolved it like bellow , but still have a littel Question. ```auto RestClient restClient = RestClient.builder( new HttpHost("localhost", 9200, "http")).build(); //RestClientBuilder builder = RestClient.builder(new HttpHost("localhost", 9200, "http")); // Map params = Collections.singletonMap("gender", "Ahoiii"); Response response1 = restClient.performRequest("GET","/try1/_doc/1"); // here is the secret RequestLine requestLine = response1.getRequestLine(); HttpHost host = response1.getHost(); int statusCode = response1.getStatusLine().getStatusCode(); //org.apache.http.Header[] headers = response1.getHeaders(); String responseBody = EntityUtils.toString( response1.getEntity()); System.out.println("result is : " + responseBody); ``` result is, ```auto result is : {"_index":"try1","_type":"_doc","_id":"1","_version":4,"found":true,"_source":{"my_id":"6","gender":"Ahoiii"}} ``` I need to write this ```auto Response response1 = restClient.performRequest("GET","/try1/_doc/1"); ``` correctly to give me all Entity with their different "\_id's" , not just the "\_doc" with "\_id =1 ". Cause in my Index there are more than one \_id . Can you please help me do this?? thx. ---

Could you express what you want to do with a full recreation script as described in [About the Elasticsearch category](https://discuss.elastic.co/t/about-the-elasticsearch-category/21). It will help to better understand what you are doing. Please, try to keep the example as simple as possible. A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer. Then when we know exactly what you want to do, we can translate that to Java code. ---

I just want to translet the Match\_all Search Query using either TransportClient in Low Level Rest Client, or RestClient in Low Level Rest Client. I want just the same Result wich this Query gives , but on my Programm Console using one of the above Low Level Clients. This Search query will give me all Content of my Index , that mean every Entity and every Field with its Value too . ```auto GET try1/_search { "query": { "match_all": {} } } ``` That is all the Idea about. thx. ---

Easiest way: ```auto try (RestHighLevelClient client = new RestHighLevelClient( RestClient.builder(HttpHost.create("http://localhost:9200")))) { SearchResponse response = client.search(new SearchRequest("test"), RequestOptions.DEFAULT); } catch (Exception e) { e.printStackTrace(System.err); } ``` Or: ```auto try (RestHighLevelClient client = new RestHighLevelClient( RestClient.builder(HttpHost.create("http://localhost:9200")))) { SearchResponse response = client.search(new SearchRequest("test") .source(new SearchSourceBuilder().query( QueryBuilders.matchAllQuery() ) ), RequestOptions.DEFAULT); } catch (Exception e) { e.printStackTrace(System.err); } ``` ---

Because you are not using the same version for the client and the server most likely. ---
