elasticsearch - ElasticSearch按完全匹配搜索电子邮件

Question

我需要通过电子邮件搜索联系人。根据ES documentation的最佳实现方法是使用uax_url_email标记器。这是我的索引设置:

settings: {
  index: {
    creation_date: "1467895098804",
    analysis: {
      analyzer: {
        email: {
          type: "custom",
          tokenizer: "uax_url_email"
        }
      }
    },
    number_of_shards: "5",
    number_of_replicas: "1",
    uuid: "wL0P6OIaQqqYpFDvIHArTw",
    version: {
      created: "2030399"
    }
  }
}

和映射:

contact: {
  dynamic: "false",
  properties: {
    contact_status: {
      type: "string"
    },
    created_at: {
      type: "date",
      format: "strict_date_optional_time||epoch_millis"
    },
    email: {
      type: "string"
    },
    id: {
      type: "long"
    },
    mailing_ids: {
      type: "long"
    },
    subscription_status: {
      type: "string"
    },
    type_ids: {
      type: "long"
    },
    updated_at: {
      type: "date",
      format: "strict_date_optional_time||epoch_millis"
    },
    user_id: {
      type: "long"
    }
  }
}

创建索引后，我插入了两个文档:

curl -X PUT 'localhost:9200/contacts/contact/1' -d '{"contact_status": "confirmed", "email": "example@gmail.com", "id": "1", "user_id": "1", "subscription_status": "on"}'

和

curl -X PUT 'localhost:9200/contacts/contact/2' -d '{"contact_status": "confirmed", "email": "example@yahoo.com", "id": "2", "user_id": "2", "subscription_status": "on"}'

然后，我尝试通过电子邮件以不同的方式搜索联系人:

curl -X POST 'localhost:9200/contacts/_search?pretty' -d '{"query": {"bool": {"must": [ {"match": {"_all": { "query": "example@google.com", "analyzer": "email" } } } ] } } }'

我预期会获得1个ID = 1的结果，但点击率却是空的:

{
  "took" : 1,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "hits" : {
    "total" : 0,
    "max_score" : null,
    "hits" : [ ]
  }
}

我测试过的下一个搜索查询是:

curl -X POST 'localhost:9200/contacts/_search?pretty' -d '{"query": {"bool": {"must": [ {"match": {"_all": { "query": "example@google", "analyzer": "email" } } } ] } } }'

返回了2个结果:

{
  "took" : 2,
  "timed_out" : false,
  "_shards" : {
    "total" : 5,
    "successful" : 5,
    "failed" : 0
  },
  "hits" : {
    "total" : 2,
    "max_score" : 0.016878016,
    "hits" : [ {
      "_index" : "contacts",
      "_type" : "contact",
      "_id" : "2",
      "_score" : 0.016878016,
      "_source" : {
        "contact_status" : "confirmed",
        "email" : "example@yahoo.com",
        "id" : "2",
        "user_id" : "2",
        "subscription_status" : "on"
      }
    }, {
      "_index" : "contacts",
      "_type" : "contact",
      "_id" : "1",
      "_score" : 0.016878016,
      "_source" : {
        "contact_status" : "confirmed",
        "email" : "example@gmail.com",
        "id" : "1",
        "user_id" : "1",
        "subscription_status" : "on"
      }
    } ]
  }
}

但是据您所知，我希望在搜索结果中得到1个文档。我究竟做错了什么？

用它来提出您的要求👍对我有用

GET my_index/_search
{
    "query": {
        "match_phrase_prefix" : {
            "email": "valery@gmail.com"
        }
    }
}

您将获得预期的结果
