Currently the contest editorial links just search for tag named by contest name, which makes editorials mixed with contest problem discussions (which often include contest named tag as well). I suggest modifying the editorial link to make the contest editorial page more cleanly.
add a new tag for each contest editorial, eg. july14ed.
search for multiple tags, eg. july14,editorial
I prefer the 2nd approach, but it needs support on multiple tag search. (maybe too complicated?)
