Advanced filter logic - ANDs before ORs?
Marketo says that it requires you use ANDs before ORs:
Use Advanced Filters in a Smart List - Marketo Docs - Product Docs
Is this correct? I feel like my smart lists have worked even if I put ORs in the beginning. Or is this a speed issue or am I misinterpreting this doc?
Example:
(1 or 2) and 3
vs.
1 and (2 or 3)
and what about:
1 and (2 or 3) and (4 or 5)
Thanks!
