A control file contains all the synonym definitions for a thesaurus. To examine the default thesaurus, create its control file using the mksyd utility. Use the syntax:
mksyd -dump -syd $SYBASE/$SYBASE_FTS/verity/common/vdkLanguage/vdk20.syd -f work_location/control_file.ctl
vdkLanguage – is the value of the vdkLanguage configuration parameter (for example, “english”)
work_location – is the directory where you want to place the control file
control_file – is the name of the control file you are creating from the default thesaurus
Examine the control file (control_file.ctl) that it creates to view the default synonym lists.
