CannedQuery. We decided - for good and bad - that canned query should be
100% transparent and carry all the state that can be easily reflected and
reached from the UI (by user selecting a department or entering search
query).  Also, the decision to not allow search string while in a
department was a deliberate design decision where departments should only
serve for browsing and as soon as you type a query, it should be global
search. I acknowledge this is problematic / limiting and I was also hit by
this while implementing some of the sopes. We plan to revisit this API to
find a solution (which will likely allow arbitrary data to be attached as I
see no other way at the moment).

to support more directly in the API and shell in the (near?) future.

It's a bit strange to have a CannedQuery constructor with both a query
sting and a department if you may not use them both.
Then I'll just wait to implement this until the revisit.

was decided for Unity 8 to show previews in practically all cases, except
for carefuly chosen exceptions (which are defined in Unity8 dash; one that
comes to my mind at the moment is Apps scope), making this API endpoint a
no-op for 99% of scopes. So yes, we need to update the documentation and
clean this part of API up, and this is also in our plans. Sorry for
confusion.
