The only release of KS that could read a Lucene (version 1.4.3) index
was 0.05, and that was only for pure ASCII source material.

The Lucene file format is gnarly -- it uses the illegal aberration
"modified UTF-8" for text encoding, it's compromised by exceedingly
complex optimizations, etc. The format wasn't originally designed to
be public; the spec was published as an afterthought. Developments
since 1.4.3 have made it even harder to work with.

Alas, sigh.

BTW, I see that version 0.20 of KinoSearch supports sorting. Cool!
