elasticsearch - 如何查询 Elasticsearch 自动完成字段，并仅返回某些结果？

Question

给定以下映射:

{
      "tags": {
        "aliases": {},
        "mappings": {
          "tag": {
            "properties": {
              "_users": {
                "type": "string"
              },
              "child": {
                "type": "string"
              },
              "level": {
                "type": "double"
              },
              "name": {
                "type": "string",
                "fields": {
                  "suggest": {
                    "type": "completion",
                    "analyzer": "simple",
                    "payloads": true,
                    "preserve_separators": true,
                    "preserve_position_increments": true,
                    "max_input_length": 50
                  }
                }
              },
              "parent": {
                "type": "string"
              },
              "root": {
                "type": "boolean"
              }
            }
          }
        },
        "settings": {
          "index": {
            "creation_date": "1443688314495",
            "number_of_shards": "5",
            "number_of_replicas": "1",
            "version": {
              "created": "1070299"
            },
            "uuid": "iH0QRRm_QF6pXEZ5sJI4yA"
          }
        },
        "warmers": {}
      }
    }

另外， _users是一个字符串数组。

如何查询标签名称建议，并仅返回在 _users数组中查询“id”的文档？

这是一个示例标记:

{
  "_index": "tags",
  "_type": "tag",
  "_id": "560b25d8276a6504d808d703",
  "_score": 1.0,
  "_source": {
    "name": "elastic indexed?",
    "child": [],
    "_users": ["foobar", "someMongoObjectID", "hellothere"],
    "_id": "560b25d8276a6504d808d703"
  }
}
