derby.system.home, or the working directory where you started derby if
derby.system.home is not defined.

We tried to see the index usage but couldn't.
did you try to set the property derby.language.logQueryPlan=true in your

-Dderby.language.logQueryPlan=true
This property when set will print the query plans in derby.log
If an index is used, you will be able to see IndexScan ResultSet....
