I used Elastic Search java client,  
I am implementing a search application.  
(Index has already been built)

I want to reproduce the Elastic Search java client, the following query.

However, it can not be reproduced.

If you are familiar with java client,  
I want you to tell me.

# The query I want to execute (sample field has java and php)

```
{
    "Query": {
        "Bool": {
            "Must": [{
                "Match": {
                    "Sample": "java"
                }},
                {"Match": {
                    "Sample": "php"
                }
            }]
        }
    },
    "Size": 50
}

```

# Assembling queries on the java client

```
BoolQueryBuilder boolQuery = QueryBuilders.boolQuery ().
        Must (QueryBuilders.matchQuery ("sample", "test")));
SearchRequestBuilder builder = client.prepareSearch ()
        .setSize (50)
        .setQuery (boolQuery);
System.out.println (builder);

```

# ↑ Output contents of "builder" variable

```
{
  "Size": 50,
  "Query": {
    "Bool": {
      "Must": [
        {
          "Match": {
            "Sample": {
              "Query": "test",
              "Operator": "OR",
              "Prefix_length": 0,
              "Max_expansions": 50,
              "Fuzzy_transpositions": true,
              "Lenient": false,
              "Zero_terms_query": "NONE",
              "Boost": 1.0
            }
          }
        }
      ],
      "Disable_coord": false,
      "Adjust_pure_negative": true,
      "Boost": 1.0
    }
  },
  "Ext": {}
}

```

When outputting, extra properties are included in match.  
Moreover, I still do not know how to match multiple words.

Someone, please lend me your wisdom.

Just call must() another time.

See [https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-compound-queries.html#java-query-dsl-bool-query](https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-compound-queries.html#java-query-dsl-bool-query)
