表格式如下
现在有多个表
我想知道多表同时查询该怎么查，还有比如某个邮箱12345@qq.com ，我输入123就能搜出包含123的所有数据该怎么查，谢谢前辈们了。

I really can’t see what it is trying to express in the second picture. I can’t see anything except a series of icons...
Enter 123 to search for all data containing 123... How to check MongoDB for other databases. In this regard, relational databases are the same as MongoDB. But as far as I know, no database seems to recommend this method of searching. Therefore, the questioner may want to review whether his needs are reasonable.
