Paul (*bows* to the NINES!) -
If you literally want Citations always at the bottom regardless of other
relevancy, then perhaps consider indexing boolean top_sort as true for
everything Citations and false otherwise, then use &sort=top_sort asc,score
desc (or do you need to desc top_sort? true then false or false then true?)
Then you can have Citations literally at the bottom (and within that sorted in
score order) and likewise with non-Citations at the top and sorted score order
within that. Other tricks still risk having Citations mixed in should
relevancy score be high enough.
The morale of this story is: if you want to hard sort by something, then make a
sort field that does it how you like rather than trying to get relevancy
scoring to do it for you.
