Question

我有一个非常简单的SQL查询：

SELECT * FROM table
WHERE 
((sphereMin>=-17 AND sphereMax<=5) OR sphereMin<=-17)
AND
((sphereMax<=5 AND sphereMax>=-17) OR sphereMax>=5)

我必须使用高级API将该查询转换为ES。这是相关代码：

 SearchSourceBuilder searchBuilder = new SearchSourceBuilder();
 BoolQueryBuilder boolQueryBuilder = boolQuery();

 BoolQueryBuilder booleanQuery1 = boolQuery();
 BoolQueryBuilder subQuery1a = boolQuery();
 booleanQuery1.must(subQuery1a);
 RangeQueryBuilder subQuery1b = null;

subQuery1a.must(rangeQuery("sphereMin").gte(-17));
subQuery1a.must(rangeQuery("sphereMax").lte(5));
subQuery1b = rangeQuery("sphereMin").lte(-17);

booleanQuery1.should(subQuery1b);

BoolQueryBuilder booleanQuery2 = boolQuery();
BoolQueryBuilder subQuery2a = boolQuery();
booleanQuery2.must(subQuery2a);
RangeQueryBuilder subQuery2b = null;

subQuery2a.must(rangeQuery("sphereMax").gte(-17));
subQuery2a.must(rangeQuery("sphereMax").lte(5));
subQuery2b = rangeQuery("sphereMax").gte(5);

booleanQuery2.should(subQuery2b);

boolQueryBuilder.filter(booleanQuery1);
boolQueryBuilder.filter(booleanQuery2);
searchBuilder.query(boolQueryBuilder);
SearchRequest searchRequest = Requests.searchRequest(indexName).allowPartialSearchResults(true)
                .source(searchBuilder).routing(routing);

从该代码创建的JSON是：

{
  "bool" : {
    "filter" : [     
      {
        "bool" : {
          "must" : [
            {
              "bool" : {
                "must" : [

                        "from" : "-17",
                        "to" : null,
                        "include_lower" : true,

                      }
                    }
                  },
                  {
                    "range" : {
                      "sphereMax" : {
                        "from" : null,
                        "to" : "5",

                      }
                    }

                  "to" : "-17",

                }
              }
            }
          ],
          "adjust_pure_negative" : true,
          "boost" : 1.0
        }
      },
      {
        "bool" : {
          "must" : [
            {
              "bool" : {
                "must" : [
                  {
                    "range" : {
                      "sphereMax" : {
                        "from" : "-17",
                        "to" : null,
                        "include_lower" : true,
                        "include_upper" : true,
                        "boost" : 1.0
                      }
                    }
                  },
                  {
                    "range" : {
                      "sphereMax" : {
                        "from" : null,
                        "to" : "5",
                        "include_lower" : true,
                        "include_upper" : true,
                        "boost" : 1.0
                      }
                    }
                  }
                ],
                "adjust_pure_negative" : true,
                "boost" : 1.0
              }
            }
          ],
          "should" : [
            {
              "range" : {
                "sphereMax" : {
                  "from" : "5",
                  "to" : null,
                  "include_lower" : true,
                  "include_upper" : true,
                  "boost" : 1.0
                }
              }
            }
          ],
          "adjust_pure_negative" : true,
          "boost" : 1.0
        }
      }
    ],
    "adjust_pure_negative" : true,
    "boost" : 1.0
  }
}

在我看来不错，但该查询未返回与SQL查询相同的数据。我在做什么错了？

Answer 1

((sphereMax<=5 AND sphereMax>=-17) OR sphereMax>=-17)

ubQuery2a.must(rangeQuery("sphereMax").gte(-17));
subQuery2a.must(rangeQuery("sphereMax").lte(5));
subQuery2b = rangeQuery("sphereMax").gte(5);

5代替-17

;）

Answer 2

以您的情况

booleanQuery1.must(subQuery1a);

应该是

booleanQuery1.should(subQuery1a);

以及

booleanQuery2.must(subQuery2a);

也应该

booleanQuery2.should(subQuery2a);

示例：

qb.should(a);
qb.should(b);
qb.should(c);

默认情况下，至少满足以下条件之一：a OR b OR c而

qb.must(a);
qb.should(b);

表示必须匹配，而b 应该。
