Elasticsearch Java API Function Score Query with script 函数

Question

我目前正在尝试使用 elasticsearch 的 Java API 构建此功能分数查询:

"query": {
"function_score": {
  "query": {
    "query_string": {
      "query": " ( ((Feild1:\"KeyWord\"^100)  OR (Feild2:\"KeyWord\"^50) ))",
      "default_operator": "and"
    }
  },
  "boost_mode": "replace",
  "script_score": {
    "script": "_score * doc [ 'calc_feild'].value"
  }
}

但是我找不到任何关于 java api 和函数分数查询的文档。这是我目前所拥有的:

到此为止

searchParam = ((Feild1:\"KeyWord\"^100)  OR (Feild2:\"KeyWord\"^50))
searchBulider.setQuery(new FunctionScoreQueryBuilder(QueryBuilders.queryString(searchParam).defaultOperator(Operator.AND)).boostMode("replace"));

查询

"query" : {
"function_score" : {
  "query" : {
    "query_string" : {
      "query" : " (  ((Feild1:\"KeyWord\"^100)  OR (Feild2:\"KeyWord\"^50) ) )",
      "default_operator" : "and"
    }
  },
  "functions" : [ ],
  "boost_mode" : "replace"
}

不知道以后的方法 下一个问题是如何在 FunctionScore Builder 中提供函数

函数为空？

谢谢

您走对了，这里是构建所需查询的完整代码:

searchParam = "((Feild1:\"KeyWord\"^100)  OR (Feild2:\"KeyWord\"^50))";
QueryStringQueryBuilder query = QueryBuilders.queryString(searchParam)
    .defaultOperator(Operator.AND);
ScriptScoreFunctionBuilder scoreFunction = ScoreFunctionBuilders
    .scriptFunction("_score * doc['calc_feild'].value");
searchBulider.setQuery(new FunctionScoreQueryBuilder(query, scoreFunction)
    .boostMode("replace"));
