Application ID: 13359975

Base Claim:
1. A computer-implemented method, comprising: selecting a regular expression from a set of regular expressions used to identify a text portion of a message; retrieving a set of one or more configuration parameters arranged to limit expansion of features of the regular expression into a set of potential regular expression key terms, at least one configuration parameter operative to determine which feature to expand and which feature not to expand; identifying a set of one or more features within the regular expression enabled by the set of configuration parameters; and generating a set of one or more identified regular expression key terms from the enabled features of the regular expression.

Claim 4:
4. The computer-implemented method of claim 1 , comprising retrieving a configuration parameter comprising an integer value to constrain expansion of a feature of the regular expression, where an integer value of greater than zero indicates a number of occurrences of the feature allowed before limiting expansion.
