ABSTRACT:
A system and method directed to a matching engine for finding the best match for an input string from among a group of predefined string patterns is disclosed. The predefined patterns may include one or more wildcard characters. A metric value is computed for every predefined string pattern. If the input string matches more than one predefined pattern, then the pattern with the highest metric value is determined as the best match to the input string. Additionally, information of different types may be attached to the predefined patterns and used for further processing of information, for example, to make routing decisions or to run a program module.
