                       "boost": 1
                   }
               }
           ],

           "adjust_pure_negative": true,
           "boost": 1
       }
   },

 "sort": { "_score": { "order": "desc" }}

}

我想先搜索确切的关键字 'template testing'，然后使用 'template' 和 'testing' 进行标记化搜索，但我的查询只搜索 'template' 和 'testing' 分开。请帮助我改进查询。

Answer 1

只需执行一个简单的匹配查询，该查询将对结果进行排序，两个术语都出现在顶部，然后是单个术语的结果。您可以使用此 link https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-match-query.html

添加其他参数

 {
  "query": {
    "bool": {
      "should": [

        {
          "match": {
            "tag": {
              "query": "template testing"
            }
          }
        },

        {
          "match": {
            "title": {
              "query": "template testing"
            }
          }
        },

        {
          "match": {
            "body": {
              "query": "template testing"
            }
         }

        }
        ]
  }
}
}
