I would like to see the possibility of adding a feature to presort
results before UDFs are called.
In reality this ONLY really needs to be able to (pre)sort by “@weight DESC”
(can use the custom ranker if want a more elaborate sorting).
After applying the UDF etc, would still want the final sort
setSortOrder order, so that can still sort by the the output of the
UDF or other attribute etc, as well as by weight.
