I think it's worth trying, but not sure if worth merging and
deploying. 0.82 didn't used directly the python xapian bindings, but
some wrapper on top of it that tried to make easier the mapping
between keys in the B-tree and metadata values.

I'm not sure if it would be easier for you to try to read the index
with the basic bindings or by using secore (now called xappy).

The mapping mentioned before is persisted in index/config inside the DS dir.
