Xapian devel - Jan 2009 - Xapian Ruby bindings do not implement full multi-value-sorting functionality?

Hello,

this is a question that could be answered by collaborators of the Ruby
bindings.
Today I've played around with the Xapian::MultiValueSorter class. I've
set
everything up and then I tried following on an instance of Xapian::Enquire:

:
enquire = Xapian::Enquire.new(database)
enquire.query = options[:query]
:
sorter = Xapian::MultiValueSorter.new
sorter.add(0, true)
sorter.add(1, true)
:
enquire.sort_by_key_then_relevance(sorter)
:

And it seems that there is no 'sort_by_key_then_relevane' method
implented
in Xapian::Enquire.
The documentation tells me:
http://www.xapian.org/docs/apidoc/html/classXapian_1_1Enquire.html#7c6c0c1f66bdeefbd09a0575584ba9b9

Is there a reason for this? How could it be implemented into the Ruby
bindings?

I've read the HACKING document that comes with the xapian-bindings but
I've
never used SWIG, I wasn't able to help myself.
Any help is highly appreciated.

Which version of Xapian are you using?

Enquire::set_sort_by_key_then_relevance() was added to the SWIG bindings on
Nov 29th 2007, and included in releases of xapian from 1.0.5 onwards.

I've not checked that it works in the Ruby bindings, but it's certainly
present in the generated xapian_wrap.cc file for Ruby.
