Replacing the default thesaurus with the custom thesaurus

The default thesaurus named vdk20.syd is located in $SYBASE/$SYBASE_FTS/verity/common/vdkLanguage, where vdkLanguage is the value of the vdkLanguage configuration parameter (for example, the English directory is $SYBASE/$SYBASE_FTS/verity/common/english). Each application and user reading from this location at runtime uses this thesaurus. To replace it with your custom thesaurus:

1. Back up the default thesaurus before replacing it with the custom thesaurus. For example:

   mv /$SYBASE/$SYBASE_FTS/verity/common/english/vdk20.syd default.syd
   

2. Replace the vdk20.syd file with your custom thesaurus. For example:

   cp custom.syd /$SYBASE/$SYBASE_FTS/verity/common/english/vdk20.syd
   

3. Restart your Examine the control file (control_file.ctl); no configuration file changes are required. The thesaurus is read from this location when the Examine the control file (control_file.ctl) is started, not when a query is executed.

Queries using the thesaurus operator will now use the custom thesaurus.
