           "dal_computer_activity_count": 5,
           "status": "verified"
        }

   "community": {
                  "type": "string"
               },

{
  "query": {
    "term": {
      "community": {
        "value": "Retail"
      }
    }
  }
}

另外，类型中的所有文档都存储了上面提到的community的值。感谢帮助。

默认情况下，您使用的是标准分析器，它将输入小写。

查询retail（小写）将产生预期的结果：

curl -XGET localhost:9200/twitter/tweet/_search -d '{
  "query": {
    "term": {
      "community": {
        "value": "retail"
      }
    }
  }
}'

结果：

{
  "took": 3,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
