Xapian discuss - Sep 2005 - Unicode and complex queries from Python

I understand that the current QueryParser is not unicode aware so I am trying to
build my own queries by stringing together various Queries with OP_*. It seems
that for anything complex, such as a three word phrase, I need to call Query
with begin and end iterators. I am not sure how to do this? (As a hack I think I
can create a document with 3 words and get its TermIterator, but that seems
circuitous.) It would be great if functions such as this would take a Python
list or iterator or Term or Query objects.

Any thoughts on when the unicode-aware QueryParser will be available?

We're having difficulties with the system used to wrap Xapian for
Python. In theory you should be able to pass a Python sequence and
have everything work as expected.

How are you passing in iterators via Python? They aren't wrapped as
far as I know...

I tried passing a list and an iterator. Both failed with the wrong number/type
of args.

I also tried creating a document and passing the termlist_begin and termlist_end
and got a segmentation fault.

Any ETA on the unicode aware QueryParser?
