### Description

Hi,  
Any help to guide me for the **code part** where the ‘users’ collection **unique indexes** (such as ‘username’ and ‘email.address’ ) are been created at? I cant find it anywhere in the code…

Most of the indexes are created here: **Rocket.Chat/app/models/server/models/Users.js** ,  
but not all of them (as I mentioned above).

Thanks in advance for your help 🙂
