場景一

搜尋發帖人userId為1或者帖子hidden為true,同時要求帖子的發帖日期絕對不為2020-12-16

GET /forum/post/_search
{
  "query": {
    "constant_score": {
      "filter": {
        "bool": {
          "should": [
            {
              "match": {
                "userId": 1
              }
            },
            {
              "match": {
                "hidden": true
              }  
            }
          ],
          "must_not": [
            {
              "match": {
                "postDate": "2020-12-16"
              }
            }
          ]
        }
      }
    }
  }
}

              "match": {
                "userId": 1
              }
            },
            {
              "bool": {
                "must": [
                  {
                    "match": {
                      "userId": 3
                    }
                  },
                  {
                    "match": {
                      "postDate": "2020-10-13"
                    }
                  }
                ]
              }
            }
