The scripts for enabling or disabling can be found in the dbscripts\features folder of the process-sql-store. The enable script creates an index which enables case-insensitive searching through lists.
To enable this feature you should run the enable script, and furthermore set the feature toggle for case insensitive search to enabled.
Like : blueriq.process-sql-store.oracle.case-insensitive-search-enabled=true
P.S. This functionality could hurt performance so use with caution.
