No, not really - the docs are not well organised for researching stuff
like that, you only really pick it up if you read them right through.
Philip's Exim4 book is also recommended reading.

You'd need to know that you needed an ACL, then understand what a
condition does, and that it's a string expansion, then find the section on
expansion variables and operators.
