Strahinja Val Markovic 52d8a1236b If query empty, Results sorted lexicographically
This change was also the root cause of the crash bug I spent two days tracking
down. The problem was that the new bool member was not added to the custom copy
ctor... since we don't really need a custom copy ctor for Result, we're going
with the compiler-provided one.
