如何在ElasticSearch的bool查詢中獲取基礎匹配查詢的分數？

Question

我有一個非常複雜的搜索，其中我基本上執行大量搜索與許多實體組中的至少一個實體相匹配的文章。

我注意到，隨着我添加更多的實體，分數急劇變化，因爲我的should子句大小增加。

這裏是我的查詢示例2個實體：

{ 
    "size": 50, 
    "track_scores": true, 
    "min_score": 0.05, 
    "sort": [ 
    { 
     "timestamp": { 
     "order": "desc" 
     } 
    } 
    ], 
    "query": { 
    "bool": { 
     "should": [ 
     { 
      "bool": { 
      "should": [ 
       { 
       "function_score": { 
        "functions": [ 
        { 
         "boost_factor": 1000000 
        } 
        ], 
        "query": { 
        "terms": { 
         "relatedProfiles": [ 
         "SomethingElse/124026966662", 
         "SomeLocation/707765" 
         ] 
        } 
        }, 
        "boost_mode": "replace" 
       } 
       }, 
       {

我怎樣才能獲得潛在的比賽是得分？或者，至少是名稱查詢下面的部分的分數？

Answer 1

也許https://elastic.co/webinars/elasticsearch-query-dsl有一些見解;後來在視頻中他談到了Dis Max查詢。

從https://www.elastic.co/guide/en/elasticsearch/reference/1.5/query-dsl-dis-max-query.html

「我們希望一次得分是最高的提升，而不是場得分總和（布爾查詢將給）相關聯的一個。」

Answer 2

您可以使用explain API。在提供查詢時，它會爲您提供有關每個文檔匹配的大量信息，以便推導出該分數。它是調試分數的完美工具。
