What is meant by "Matchcode"?
Matchcodes are defined in two stages in Abap/4 Dictionary:

2) One or more matchcode ID can be defined for a matchcode object. A matchcode ID describes a special search path for a search term.The fields or combination of fields via which the search is to take place is defined in the matchcode ID.
