Why on earth would you start with this crazy Lucene class ;) Alas I don't think there's any additional documentation for it, and it is really hairy.
It's basically a simplistic filesystem, where each unique term we've seen (for one in-memory segment) is a "file", and we don't know when we first see each term how many bytes it will use up, so we give it a small slice of the big byte[] store to begin. Once it fills up that slice, we give it a bigger slice, leaving a pointer at the end of the first slice pointing to where the second slice starts, etc. Then, when it's time to flush, we can sequentially read all bytes for a given term, using the initReader to get the reader.
