FacetExample.py's indexes are too old

[Andi Vajda]

  Hi Thomas,

As you may have noticed, PyLucene is being refreshed to Lucene 6.2.0.
The FacetExample.py sample you submitted to PyLucene is using an index from
Lucene version 2, FacetExample.Index.

Sadly, Lucene 6 no longer supports that version, it must be at least version
4. Could you please refresh FacetExample.Index ? (and FacetExample.Taxonomy
looks like needing that too).

Thanks !

Andi..
