I have used it at many occasions and always could do
everything I wanted.
two exemples:
1 & 2 : would select the atoms crossing the two groups 1 
and 2.
1 | 2: would select atoms from two groups 1 and 2.

and so on. But you can also write a script to generate
your own group and insert it in the index.
