Sorting by meta_value

Hi,

I’m having trouble sorting posts.

This works (I’m using it from the parse_query filter):

$query->set('orderby', 'post_date');
$query->set('order', 'DESC');

But this (with works for non-relevanssi queries) does nothing:

$query->set('meta_key', 'my_meta_field');
$query->set('orderby', 'meta_value');
$query->set('order', 'DESC');

Is there a way to do this? Or is this just not possible with relevanssi?

Thanks,
Tom
