Xindice use different db setting, could it be possible?

[Jerry Tan]

hi, all.
I want to use xindice as local database for one swing based desktop 
application.
the application support multiple users.
so I want to set xindice 's db diretory under the user's home diretory,
   such as $HOME/.xindice/db

so when  different user start  the application,
xindice will start from his $HOME diretory's db setting.
Is it possible?
if so, how to enable it?
Thanks.
