If you're interested in the binary format of the index files:

	Witten, Ian H.; Moffat, Alistair; Bell, Timothy C. (1999). Managing Gigabytes. Morgan Kaufmann Publishing, San Francisco, 2nd edition.

The CWB index design follows this book almost to the letter.  There's no formal specification of the precise file format, but you can find some additional remarks in this presentation:

Hope this helps,
