我的 Elasticsearch 查询有什么问题？

Question

我需要同时进行 multi_match 和 bool 查询，但下面的查询不起作用 :( 当我单独使用它们时，它们工作得很好。

{
  "query": {
    "multi_match": {
      "query": "kotlety*",
      "fields": [
        "name"
      ]
    },
    "bool": {
      "filter": {
        "term": {
          "status": 2
        }
      }
    }
  },
  "size": 24
}

响应是：

{
    "error": {
        "root_cause": [
            {
                "type": "parsing_exception",
                "reason": "[multi_match] malformed query, expected [END_OBJECT] but found [FIELD_NAME]",
                "line": 9,
                "col": 5
            }
        ],
        "type": "parsing_exception",
        "reason": "[multi_match] malformed query, expected [END_OBJECT] but found [FIELD_NAME]",
        "line": 9,
        "col": 5
    },
    "status": 400
}

Elastic 6.6，我想我的查询可能有错误的语法？

Answer 1

我更改了语法并且此查询有效：

{
  "query": {
    "bool": {
      "must": {
        "multi_match": {
          "query": "kotlety*",
          "fields": [
            "name"
          ]
        }
      },
      "filter": {
        "term": {
          "status": 2
        }
      }
    }
  }
}

Answer 2

查询不能同时包含布尔值和 multi_match。你可以这样重新排列它：

{
  "query": {
    "bool": {
      "filter": {
        "term": {
          "status": 2
        }
      },
      "should": {
        "multi_match": {
        "query": "kotlety*",
        "fields": [
          "name"
        ]
      }
    }
  }
  },
  "size": 24
}
