 The following parameters are configurable:
 
 `collections`::
-A comma-separated list of collection names. If this list is not empty then
-the computed operations will only calculate collection operations that affect
-listed collections and ignore any other collection operations for collections
+A comma-separated list of collection names. This can also be a selector on the collection property e.g. `collections: {'policy': 'my_custom_policy'}` will match all collections which use the policy named `my_customer_policy`.

Review comment:
       Thanks. I expanded the description a bit. I added another example that I am not really happy with -- I cannot think of a use-case where something other than policy might be useful especially given the fact that values must match exactly. Suggestions welcome.
