Explore / browse Lucene index by Hibernate search

Is there any way to browse / explore Lucene index created by Hibernate Search? I am aware of Luke embedded inside Lucene bundle, but such a shitty software is unable to open my index. Here is what I have:

Any attempt to open my index end up with an exception such a "Unknown error" or such a nonsense. Also I don't know what directory implementation I have as I use Hibernate Search without configuring directory implementation. Thanks!

EDIT: Tried all options and directory implementations with older Luke 5.5.0 as adviced by @andrewjames, but no luck.

P.S. The index is only 500 KB of size and I'm willing to share it with anyone who can give it a try.

Well, the magic answer it to restart Luke after each failed attempt to open a directory. Once you get an exception, close Luke and start it again.
