  $criteria->groupId = array(1, 3);
  $users = $criteria->find();

  I tried to add the admin attribute, but this hasn't changed anything:
  
  ```php
  $criteria->admin = array(false, true);
  
  ```
  
  I assume that's because the [ElementCriteriaModel](http://buildwithcraft.com/docs/templating/elementcriteriamodel) has to match all attributes, but there isn't an admin which has a UserGroup with the ID 1 or 3. But how can I tell the criteria to perform a "OR" fetch?
  
  P.S. I know I could merge two fetched criterias but I want to use a "clean" solution.

  You won't be able to do that using the `ElementCriteriaModel` or a single query (unless you use `craft ()-> db-> createCommand()` or `\CDbCriteria` to perform a conditional `JOIN`).
  
  You will either have to 1) do **post filtering** or 2) get the `ids` for users in the groups you want and the `ids` for all admin users (which I would recommend). You can then merge both arrays and use the resulting array to get all users that match the containing `ids`.
  
  You mentioned that you wanted to do it the **clean** way and doing a couple of queries using the public Element Query API is definitely the clean way to do it and the fact that you're doing a couple of queries to get the users you want should not feel **"unclean"** because that is happening in a lot of different places behind the scenes when you use the API instead of raw queries.
  
  For example, when you add the `$ criteria->groupId = array(1, 3);` to a user query, Craft will hit the db once to get all `ids` for users in those groups and then hit it again as many times as necessary to do what it needs to do, like perform searches and such.
