Currently, running an
aggs
query that is valid but returns no results is handled in a kind-of weird way. This PR just addresses it directly, catching the empty case and logging out the fact that it was empty with anINFO
level statement.I don't think this fixes the issue that was reported in #58 (since that turned out to actually be about
reverse_nested
aggs), but gets us a bit closer.
