我正在尝试使用 

query_string
在电子邮件字段中搜索以下字符串 r@hot。我期待它返回以下数据，

    [{
    "_index": "test_company",
    "_type": "_doc",
    "_id": "9303000d-b167-4d7c-b233-43a43c4a7e60",
    "_score": 2.4849067,
    "_source": {
        "id": "9303000d-b167-4d7c-b233-43a43c4a7e60",
        "name": "My Property Company",
        "phone": "11484473106",
        "email": "[email protected]",
        "website": "https://www.walmart.com",
        "ein": "731087415",
        "address": "Apt. 837 5371 Carroll Estates, Zboncakbury, LA 53957-3670",
        "zip": "99950",
        "city": "Ketchikan",
        "state": "Alaska",
        "country": "US",
        "fileId": "",
        "status": "Active"
    }
}]

但是它是返回上面的所有数据 ...

到目前为止，我尝试了很多组合，其中两个是以下组合，

{
  "query": {
    "bool": {
      "must": [
        {"query_string": {
          "query": "r@hot*", 
          "fields": ["email"],
          "analyze_wildcard": true
        }}
      ]
    }
  }
}

结果：返回所有数据

{
  "query": {
    "bool": {
      "must": [
        {"query_string": {
          "query": "*r@hot*", 
          "fields": ["email"],
          "analyze_wildcard": true
        }}
      ]
    }
  }
}

结果：它什么都不返回

还有其他方法可以完成我需要的吗？

node.js elasticsearch search query-string opensearch

长话短说；

这是您撞到文本分析器管道的情况。

email
是 
text
类型的字段。 应用默认文本分析器。

了解

您可以使用以下api调用：

GET /_analyze
{
  "analyzer" : "standard",
  "text" : "[email protected]"
}

送给你

{
  "tokens": [
    {
      "token": "johnie.schinner",
      "start_offset": 0,
      "end_offset": 15,
      "type": "<ALPHANUM>",
      "position": 0
    },
    {
      "token": "hotmail.com",
      "start_offset": 16,
      "end_offset": 27,
      "type": "<ALPHANUM>",
      "position": 1
    }
  ]
}

确实是两个代币。

但是当您要针对

email
字段执行查询时。您的查询也将使用管道。

如果您要在查询中使用

explain
标志，您会注意到它。

GET 75680788/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "query_string": {
            "query": "r@hot*",
            "fields": [
              "email"
            ],
            "analyze_wildcard": true
          }
        }
      ]
    }
  },
  "explain": true
}

你得到：

      }
    ]
  }
}

您得到 2 个查询，

(email:r email:hot*)
，默认情况下应用 
OR
运算符。

解决方案

我建议你使用类型

keyword
，这应该有效。

GET 75680788/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "query_string": {
            "query": "*r@hot*",
            "fields": [
              "email.keyword"
            ],
            "analyze_wildcard": true
          }
        }
      ]
    }
  },
  "explain": true
}
