Name of related component: Core Reporting API
Request summary:
I would like to propose a feature that allows for the setting of which boolean
precedence one would prefer in an expression. This could be accomplished with
the current reserved characters and would not break any existing filters -
placing ";," at the beginning of the filter or segment string would indicate an
AND over OR precedence, while placing ",;" would indicate the current OR over
AND precedence (which or course would remain the default).
Reason for feature:
Currently dynamic segments and filters have a precedence of OR over AND. This
is contrary to the standard boolean algebraic precedence of AND over OR.
Currently there are many expressions which simply cannot be accommodated by the
API - for instance AB+CD. The reporting API will interpret this as A(B+C)D
which is incorrect. Since every boolean expression can be reduced to a series
or terms, for instance (A+B)(C+D)=AB+AC+BC+BD, having AND over OR would allow
any boolean expression to be calculated by the API without the need for
grouping. (AB+CD cannot be reduced or expanded to an expression which evaluates
the same in an OR over AND precedence).
Use Cases:
Utilization of complex boolean expressions in dynamic segments and filters that
cannot currently be accomplished with the existing precedence rules.
