Hi All,
I've just started digging into this as well. Its really unfortunate to only
get "relevance" results for searches.
In digging in, I've spit out the stack trace, and its telling me a few
things.
1) Do we have "bad" metadata for dc.date.issued?
-- (I've already harassed my content folks to have them review all our
metadata) ;)
2) Are we doing the comparison of dates incorrectly. The error below says
is the value of "dateissued" an INT.
-- I've been reading this thread, which is very similar:

Just for fun, I enabled Discovery on our development machines, and sorting
by date issued works perfectly in a search. So, a quick-fix would be to
switch to using discovery. But, none-the-less, I look forward to getting a
resolution to this issue.
