如何將這個彈性搜索功能得分查詢轉換爲java API

Question

如何將下面的ES查詢轉換爲Java API？我使用的彈性搜索2.3.3

GET /schema_name/_search 
{ 
"from": 0, 
"size": 200, 
"query": { 
    "function_score": { 
     "query": { 
      "match_all": {} 
     }, 
     "boost": "5", 
     "functions": [{ 
       "filter": { 
        "term": { 
         "alert_code": "event_rule_1" 
        } 
       }, 
       "weight": 50 
      }, 
      { 
       "filter": { 
        "term": { 
         "alert_code": "event_rule_2" 
        } 
       }, 
       "weight": 30 
      }, 
      { 
       "filter": { 
        "term": { 
         "alert_code": "event_rule_3" 
        } 
       }, 
       "weight": 10 
      }, 
      { 
       "filter": { 
        "term": { 
         "alert_code": "event_rule_4" 
        } 
       }, 
       "weight": 10 
      }, 
      { 
       "filter": { 
        "term": { 
         "alert_code": "event_rule_5" 
        } 
       }, 
       "weight": 50 
      }, 
      { 
       "filter": { 
        "term": { 
         "alert_code": "event_rule_6" 
        } 
       }, 
       "weight": 50 
      } 
     ], 
     "max_boost": 50, 
     "score_mode": "max", 
     "boost_mode": "replace", 
     "min_score": 0 
     } 
    } 
} 

我已經嘗試過寫這ES查詢中使用的Java API使用下面 Elasticsearch FunctionScore query using Java API

鏈接，但下面的鏈接似乎是一個較舊的ES版和我無法在彈性搜索2.3.3中找到這些靜態函數。

取得它如下面使用Java API

FunctionScoreQueryBuilder functionScoreQueryBuilder = QueryBuilders 
        .functionScoreQuery(queryBuilder) 
        .setMinScore(0f) 
        .maxBoost(50f) 
        .scoreMode("max") 
        .boostMode(CombineFunction.REPLACE); 

      for (String alertCode : ruleCodesLowerCase) { 
       if(alertPriorityMap.get(alertCode.toUpperCase()) != null){ 
        functionScoreQueryBuilder.add(QueryBuilders.termQuery(AlertESEnum.ALERT_CODE_FIELD.value(), 
          alertCode), ScoreFunctionBuilders.weightFactorFunction((AlertPriority.intValue(alertPriorityMap.get(alertCode.toUpperCase()).getPriority())))); 
       } 
      }
