Hi Jason,
Thanks for the advice.
However I was just working through the example. I actually don't want to
search on numbers / dates / geo etc and was looking at custom sorting.
It appears that custom sorting, or even sorting for that matter is not
useful if every document will have sorting applied against it before the
document filter even hits.
Is there no way to limit the sorting to only the documents that were found
in the query?
Thanks
