原生rest：
对“不好”进行分词， "operator": "and"意思是同时满足。

POST corpus_details_22/_search
{
  "query": {
    "dis_max": {
      "queries": [
        {
          "match": {
            "sourceContent": {
              "query": "不好",
              "operator": "and"
            }
          }
        }
      ]
    }
  }
}
