Managing Rule Set Overhead

One way of managing the overhead on executing rule sets is to add a conditional expression to the rule set that evaluates to FALSE when the rule set is unlikely to return any records. This action skips the rule set whenever it is unlikely to find content.

For example, as shown in Table 24, rule set 1 is based on the user's age as calculated from his or her birthday and rule sets 2 and 3 are based on other information.
