The system determines one or more overlapping Boolean expressions between the first set and the second set. Each Boolean expression has a corresponding identifier and priority, and two or more Boolean expressions overlap when the Boolean expressions have an identical identifier. Each set of Boolean expressions includes a corresponding index. ## Claims ### Claim 1 A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to evaluate Boolean expressions to determine a functionality of an ecommerce website, the evaluating comprising: receiving a first set of Boolean expressions comprising a first plurality of unique Boolean expressions, each Boolean expression having an associated identifier and payload and comprising a first Boolean expression having an associated first identifier, wherein the payload comprises a value that is returned when a corresponding Boolean expression is satisfied;
