This document is a good starting point:

http://xapian.org/docs/matcherdesign.html

I've just updated it to more accurately reflect the current status, but
it may still be wrong in a few details.  The overall picture is accurate
though.

There are other useful links here:

http://xapian.org/docs/internals.html

The "internal classes" link allow you to browser most of the internal
classes, for example here's MultiAndPostList:
