Review comment:
Discussed offline with @mqliang
As suggested in the previous comment, let's not fix the BYTES problem in
this PR. We can investigate and fix that separately. The url encoding for (with
and without *) and that corner case problem for a particular problem should be
fixed (which @mqliang found out is due to min/max value being null and server
throwing NPE).
Let's make sure to add tests for with and without encoded query string --
everything after columns= can be encoded. I think in this PR, controller is
re-encoding. We should remove that
