Creating ElasticSearch 6.5 nested boolean queries from SQL

[Daniele_Renda]

I've this quite simple SQL query:

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

I have to translate that query to ES using high level API. This is the relevant code:

 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);

The JSON created from that code is:

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

                  "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
  }
}

It looks right to me but that query doesn't return the same data of the SQL query. What am I doing wrong?
