已经解决，能成功通过接口访问获得结果
仿monggo原始语句，测试版，还没有规范代码，相信能够看懂。
List<Document> dbObjects = new ArrayList<>();
Document limit = new Document();
Document project = new Document();
Document condition = new Document();
Document project2 = new Document();
Document condition2 = new Document();
Document sort = new Document();
condition.put("title", 1);
List<Object> listIntersects = new ArrayList<>();
listIntersects.add(words);
listIntersects.add("$mapDarkTitle.word");
condition.put("commonToBoth", new Document("$setIntersection", listIntersects));
project.put("$project", condition);
condition2.put("title", 1);
condition2.put("commonToBoth", 1);
condition2.put("commonToBothSize", new Document("$size", "$commonToBoth"));
project2.put("$project", condition2);
sort.put("$sort", new Document("commonToBothSize", -1));
limit.put("$limit", 20);
dbObjects.add(project);
dbObjects.add(project2);
dbObjects.add(sort);
dbObjects.add(limit);
AggregateIterable<Document> re = mongoTemplate.getCollection("hb_question_standards2")
.aggregate(dbObjects);
List<Document> listDocument = new ArrayList<>();
for (Iterator<Document> it = re.iterator(); it.hasNext();) {
Document dbo = it.next();
listDocument.add(dbo);
}
