Java APIを使用したElasticsearch FunctionScoreクエリの使用方法

Question

Java APIを使用して以下のfunction_scoreクエリを実装する必要があります。私はこの

RangeQueryBuilder queryStartDate = QueryBuilders.rangeQuery("startTime").gte(param.getStartTime()) 
       .lte(param.getEndTime()); 

     RangeQueryBuilder queryEndDate = QueryBuilders.rangeQuery("endTime").gte(param.getStartTime()) 
       .lte(param.getEndTime()); 

// query 
QueryBuilder querys = QueryBuilders.boolQuery().must(queryStartDate).must(queryEndDate); 

// function 
Map<String, Double> locationMap = new HashMap<String, Double>(); 
     locationMap.put("lat", param.getLat()); 
     locationMap.put("lon", param.getLng()); 
     ScoreFunctionBuilder sfb2 = ScoreFunctionBuilders.gaussDecayFunction("location", locationMap, "1km") 
       .setOffset("2km"); 

//function_score 
FunctionScoreQueryBuilder sa = new FunctionScoreQueryBuilder().boostMode("replace").add(sfb2); 

//final search 
SearchResponse response = client.prepareSearch().setIndices("film").setTypes("data").setQuery(sa) 
       .setQuery(querys).setSize(40).execute().actionGet(); 

のようなJava APIを使用しelasticsearch

{ 
    "size": 40, 
    "query": { 
    "function_score": { 
     "functions": [ 
     { 
      "gauss": { 
      "location": { 
       "origin": { 
       "lat": 39.99606, 
       "lon": 116.480484 
       }, 
       "offset": "2km", 
       "scale": "3km" 
      } 
      } 
     } 
     ], 
     "score_mode": "sum", 
     "boost_mode": "replace", 
     "query": { 
     "bool": { 
      "must": [ 
      { 
       "range": { 
       "startTime": { 
        "from": "2016-04-12T12:00:00.000Z", 
        "to": "2016-04-12T16:00:00.000Z", 
        "include_lower": true, 
        "include_upper": true 
       } 
       } 
      }, 
      { 
       "range": { 
       "endTime": { 
        "from": "2016-04-12T12:00:00.000Z", 
        "to": "2016-04-12T16:00:00.000Z", 
        "include_lower": true, 
        "include_upper": true 
       } 
       } 
      } 
      ] 
     } 
     } 
    } 
    } 
} 

のJava APIのセクションでfunction_scoreクエリのための任意の公式ドキュメントを見つけることができなかったが、それは

Answer 1

あなたが必要と動作しない線量次のようにFunctionScoreQueryBuilderにクエリを追加してください。

FunctionScoreQueryBuilder fqBuilder = QueryBuilders.functionScoreQuery(querys); 
    fqBuilder.boostMode(CombineFunction.REPLACE); 
    fqBuilder.scoreMode(ScoreMode.Sum.name().toLowerCase()); 
    fqBuilder.add(sfb2); 
    SearchResponse response = client.prepareSearch().setIndices("film").setTypes("data").setQuery(fqBuilder).setSize(40).execute().actionGet(); 

Answer 2

In Ela sticSearch 5.xではこれが変更され、FunctionScoreQueryBuilder.add（）メソッドは削除されました。このページにはいくつかの例があります：https://www.elastic.co/guide/en/elasticsearch/client/java-api/current/java-compound-queries.html#java-query-dsl-function-score-query
