See htcommon/DocumentRef.h if you want to know what fields are stored
in the document database. Yes, we probably need to write up a doc on
the database formats, but in the 3.2 development this changed fairly
frequently.

The DocHead is the entire stored excerpt--essentially the file
stripped of any markup. The entire field is compressed with zlib.

I don't think so. This is one reason I suggested an XS module might
help. It could call the C++ routines directly, forgoing any need to
decode the compiled-in defaults. Then again, I'm not much of a Perl
expert.
