java - Java QueryBuilders 的嵌套 Elasticsearch 查询

Question

我正在尝试在用于 elasticsearch 的 java querybuilder 中实现此 elasticsearch 查询。但我无法获得相同的结果。有人能帮忙吗。

 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"
                         }
                      }
                   }
                }
             ]
          }
       }
    }

我试过的代码:

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

您还需要添加嵌套查询。使用以下代码:

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

对于更高版本，您可以使用:

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

注意:在 6.7 中，即使文档保持 ScoreMode 是可选的，您也可能需要在使用 java QueryBuilders 时提供此参数。
