Aggregate Operators by Stage

Does anyone know if there is a list or table that shows what operators are valid for what stages? I was trying to include a $substrCP operator in a $match stage. Thanks.


I believe such a list does not exist. This is not what you asked for, but may be helpful:

Thanks. I am very familiar with that link. It is one of my favorite bookmarks.
