java - 从 java elasticsearch querybuilder 中删除默认字段

Question

Elasticsearch Java 客户端的 QueryBuider 实例正在添加属性，例如
1) order
2) min_doc_count
3) shard_min_doc_count
4) show_term_doc_count_error
5) lang
6) gap_policy

到最后的 Json 查询。没有这些属性，我的查询按预期工作。我想防止这些属性被添加到我的最终查询中。

爪哇：

FilterAggregationBuilder aggregation = AggregationBuilders.filter("id", QueryBuilders.termsQuery("id",
                        "my-name"));
TermsAggregationBuilder lev1Agg = AggregationBuilders.terms("id").field("id");
lev1Agg.size(1);               
lev1Agg.subAggregation(AggregationBuilders.sum("familyMemberCount").field("membersInFamily"));                
lev1Agg.subAggregation(AggregationBuilders.sum("totalKidsInFamily").field("kidsInFamily"));
Map<String, String> bucketsPathsMap = new HashMap<>();
bucketsPathsMap.put("familyMemberCount", "familyMemberCount");
bucketsPathsMap.put("totalKidsInFamily", "totalKidsInFamily");
Script script = new Script("params.familyMemberCount / params.totalKidsInFamily");

BucketScriptPipelineAggregationBuilder bs = PipelineAggregatorBuilders
                        .bucketScript("myScript", bucketsPathsMap, script);

lev1Agg.subAggregation(bs);
aggregation.subAggregation(lev1Agg);
searchSourceBuilder = new SearchSourceBuilder().aggregation(aggregation);
searchSourceBuilder.size(0);

上面代码构建的查询
