Configuring lucene search on V2.1.19

I need to configure orientDb integrated Lucene search to accept search queries with a leading wildcard. Something like “ziobello”.
This is easily done with v 3.0 but I can’t find a way to enable this little feature on V2.1.19.
Unfortunately, moving to V3 is not an option.

Is there a little unknown parameter I can use?
Or something in a configuration file?
As an extreme solution I could even patch the orientDb sources for my specific needs, but I’d need some pointers to know where to apply this little change.
