elasticsearch - 如何将simplequerystring与bool/must结合

Question

我有ES版本7的这个ElasticSearch查询:

{
  "from": 0,
  "simple_query_string": {
    "query": "*"
  },
  "query": {
    "bool": {
      "must": [
        {
          "term": {
            "organization_id": "fred"
          }
        },
        {
          "term": {
            "assigned_user_id": "24584080"
          }
        }
      ]
    }
  },
  "size": 50,
  "sort": {
    "updated": "desc"
  },
  "terminate_after": 50,
}

但是ES给了我这个错误:

reason: Unknown key for a START_OBJECT in [simple_query_string]

我的目标是能够对多个字段使用查询字符串，并且还可以将术语/匹配与 bool(boolean) /必须一起使用。我应该放弃查询字符串而只使用bool.must[{match:"my query"}]吗？

Answer 1

您可以使用bool以这种方式组合多个查询。 must子句将作为逻辑AND，并确保所有条件都匹配。
您需要在查询部分内包含simple_query_string
添加带有示例文档和搜索查询的工作示例。
索引样本数据

{
  "organization_id": 1,
  "assigned_user_id": 2,
  "title": "welcome"
}{
  "organization_id": 2,
  "assigned_user_id": 21,
  "title": "hello"
}{
  "organization_id": 3,
  "assigned_user_id": 22,
  "title": "hello welocome"
}

搜索查询:

    {
  "query": {
    "bool": {
      "must": [
          {
          "simple_query_string": {
            "fields" : ["title"],
            "query" : "welcome"
          }
        },
        {
          "match": {
            "organization_id": "1"
          }
        },
        {
          "match": {
            "assigned_user_id": "2"
          }
        }
      ]
    }
  }
}

搜索结果:

"hits": [
        {
            "_index": "my_index",
            "_type": "_doc",
            "_id": "1",
            "_score": 3.0925694,
            "_source": {
                "organization_id": 1,
                "assigned_user_id": 2,
                "title": "welcome"
            }
        }
    ]
