Mongodb的常用语句

模糊查询  regex(".*?\\"+questionContent+".*")

        String questionContent = "需求";
        Query query = new Query();
        query.addCriteria(Criteria.where("demandName").regex(".*?\\"+questionContent+".*"));
        
        System.out.println(mongo.count(query, AdvTrusteeship.class));

 Pattern pattern = Pattern.compile("^.*" + situation.getTitle() + ".*$", Pattern.CASE_INSENSITIVE);
 query.addCriteria(Criteria.where("title").regex(pattern));
