You can define classes to connect to a custom match engine instead of the Sun Match Engine. Specify the names of the custom classes you create in the matcher-api and matcher-config elements of the Match Field file. Follow these guidelines when implementing custom match engine classes.
Implement the com.stc.eindex.matching.MatcherAPI interface to communicate with the match engine.
Implement the com.stc.eindex.matching.MatchEngineConfiguration interface to retrieve any configuration values the match engine requires for initialization.
