Java QueryBuilders的嵌套elasticsearch查詢。

Question

我想在elasticsearch的java querybuilder中實現這個elasticsearch查詢。但我無法獲得同樣的結果。有人能幫忙嗎。

GET /XX/XX/_search 
    { 
     "query": { 
      "bool": { 
      "must": [ 
       { 
        "nested": { 
         "path": "XX", 
         "filter": { 
         "term": { 
          "A": "7:140453136:T" 
         } 
         } 
        } 
       }, 
       { 
        "nested": { 
         "path": "XX", 
         "filter": { 
         "term": { 
          "B": "RF" 
         } 
         } 
        } 
       }, 
       { 
        "nested": { 
         "path": "XX", 
         "filter": { 
         "term": { 
          "C": "RFFF" 
         } 
         } 
        } 
       } 
      ] 
      } 
     } 
    } 

我試圖代碼：

QueryBuilders qbWithArguments = QueryBuilders.boolQuery() 
        .must(QueryBuilders.termQuery("A", "RF")) 
        .must(QueryBuilders.termQuery("B", "EF")) 
        .must(QueryBuilders.termQuery("C", "RF")); 

Answer 1

您需要添加nested query了。使用下面的代碼：

QueryBuilders.boolQuery().must(nestedQuery("XX", FilterBuilders.termFilter("A","RF"))) 
          .must(nestedQuery("XX", FilterBuilders.termFilter("B","EF"))) 
          .must(nestedQuery("XX", FilterBuilders.termFilter("C","RF"))) 

對於更高的版本，你可以使用：

QueryBuilders.boolQuery().must(nestedQuery("XX", QueryBuilders.boolQuery().should(QueryBuilders.termQuery("A","RF")) 
      .should(QueryBuilders.termQuery("B","EF")).should(QueryBuilders.termQuery("C","RF")).minimumShouldMatch("1")))
