Collection level Permission

[Antony A <an...@gmail.com>]

Hi,

I am trying to find some help with the format of the collection name under
permissions.

The collection can be "*", "null", "collection_name". Is there a way to
group a set of collections?

example:

This format is not working.

{"collection": ["colname1, colname2, colname3"], "path": "/select", "role":
["dev"], "index": 1},

Thanks,
Antony
