Question

我已将here提供的数据加载到弹性搜索中。

现在我正在尝试查询帐户。

年龄必须是38岁。
国家不应该是“身份证”。
地址应包含 :(这不起作用）
- 文字“lane”或
- 完整的文字“mill avenue”

请求：POST - http://localhost:9200/bank/account/_search?pretty

{
  "query": {
    "bool": {
      "should": [
        { "match": { "address": "lane" } },
        { "match_phrase": { "address": "mill avenue" } }
      ],
      "must": [
        { "match": { "age": "38" } }
      ],
      "must_not": [
        { "match": { "state": "ID" } }
      ]
    }
  },
  "from": 0,
  "size": 1,
  "_source": ["account_number", "balance", "firstname", "lastname", "age", "email", "address", "state"],
  "sort": [
    { "account_number": "asc" },
    { "balance": "desc"}
  ]
}

  "took": 8,
  "timed_out": false,
  "_shards": {
    "total": 5,
    "successful": 5,
    "failed": 0
  },
  "hits": {
    "total": 36,
    "max_score": null,
    "hits": [
      {
        "_index": "bank",
        "_type": "account",
        "_id": "21",
        "_score": null,
        "_source": {
          "account_number": 21,
          "firstname": "Estella",
          "address": "859 Portal Street",
          "balance": 7004,
          "state": "WV",
          "age": 38,
          "email": "estellapaul@zillatide.com",
          "lastname": "Paul"
        },
        "sort": [
          21,
          7004
        ]
      }
    ]
  }
}

您可以查看回复。收到地址“859 Portal Street”的记录，不包含“lane”或“mill avenue”。

---- ----编辑 解决方案（感谢@Lax和@mattweber发布here）：如果必须/ must_not，则需要minimum_should_match。

{
  "query": {
    "bool": {
      "minimum_should_match": 1,
      "should": [
        { "match": { "address": "avenue" } },
        { "match_phrase": { "address": "Williams Place" } }
      ],
      "must": [
        { "match": { "age": "38" } }
      ],
      "must_not": [
        { "match": { "state": "ID" } }
      ],
      "filter": {
        "range": {
          "balance": {
            "gte": 20000,
            "lte": 30000
          }
        }
      }
    }
  },
  "from": 0,
  "size": 1000,
  "_source": ["account_number", "balance", "firstname", "lastname", "age", "email", "address", "state"],
  "sort": [
    { "account_number": "asc" },
    { "balance": "desc"}
  ],
  "aggs": {
    "group_by_state": {
      "terms": {
        "field": "state.keyword"
      },
      "aggs": {
        "average_balance": {
          "avg": {
            "field": "balance"
          }
        }
      }
    }
  }
}

Answer 1

必须/必须不存在时，您需要添加：

minimum_should_match" : 1

后面的数组

当“should”，“must”和“must_not”子句出现时，Elastic Search“should”子句不能按预期工作
