&& and 'and' have different precendence that's the only difference, but in
your case it doesn't matter.
what exactly are you trying to do? Your code reads
if @dates has data
and the other two BOTH do not have data
then do somthing with @dates
else if the above is false and
@dates has no data and
@themes does have data AND
@cities doesn't have data
then do something with themes.
