elasticsearch golang 的多字段搜索查询

Question

I have a situation where I need to do elastic search based on multi-field. For Example: I have multiple fields in my postindex and I want to apply condition on four these fields (ie userid , channelid , createat , teamid ) to meet my search requirement. When value of all these fields matched then search query displays results and if one of these is not match with values in postindex then it display no result.

I am trying to make a multifield search query for go-elasticsearch to search data from my post index . For the searcquery result four field must match otherwise it display 0 hit/no-result.

So, I think you need to write a following query:

GET postindex/_search
{
  "query": {
    "bool": {
      "minimum_should_match": 1,
      "should": [
        {
          "bool": {
            "must": [
              {
                "term": {
                  "userid": {
                    "value": "mcqmycxpyjrddkie9mr13txaqe"
                  }
                }
              },
              {
                "term": {
                  "channelid": {
                    "value": "dnoihmrinins3qrm6bb9175ume"
                  }
                }
              },
              {
                "range": {
                  "createat": {
                    "gt": 1672909114890
                  }
                }
              }
            ]
          }
        },
        {
          "term": {
            "teamid": {
              "value": "qomrg11o8b8ijxoy8hrcnweoay"
            }
          }
        }
      ]
    }
  }
}

In here, there is a bool query with should in parent scope, which is like OR. And inside the should there is another bool query with must which is like AND. We can also write the query shorter, but this will be better for you to understand.
