Using parentheses to set Boolean precedence in analytics RDL
You can use parentheses to set Boolean precedence in your rules. Consider a case in which you want to mark or tag the items that match these conditions:
The sender is John Doe or the recipient is Jane Smith.
The email subject must contain the word Veritas.
To match these items, one user might use the visual rule builder to construct the following rule:
Author CONTAINS '"John Doe"' OR To CONTAINS '"Jane Smith"' AND Subject CONTAINS 'Secret'
However, another user might construct the rule differently, and produce this result:
To CONTAINS '"Jane Smith"' AND Subject CONTAINS 'Secret' OR Author CONTAINS '"John Doe"'
In both cases, it is unclear what results are produced when the rule engine processes the rules. To ensure that your rules produce the results that you want, write them directly in RDL and use parentheses to group the conditions that belong together. The parentheses ensure that related conditions are evaluated as you intend, and it is clear what your intentions are. For example:
( Author CONTAINS '"John Doe"' OR To CONTAINS '"Jane Smith"' ) AND Subject CONTAINS 'Secret'
