Please consider adding the ability to specify operators for the Rule Conditions. The operator could be specified in the text field for a given Condition, for instance:
Comment text > Contains > toner or ink
The "or" being the operator.
Another way to implemnt this would be to allow us to specify a "AND" or "OR" operator between multiple Conditions:
Condition 1: Comment text > Contains > toner
or (this could be implemented as a drop-down)
Condition 2 Comment text > Contains > ink
