Hi,

RangeFaceting computation was working fine while adding numeric Ranges in
DrillDownQuery. And this is not my issue.

My question is,

I need to compute string facets (via SortedSetDocValuesFacetCounts) using
drill sideways search by adding numeric Ranges in DrillDownQuery... This
case only throws an exception. Is it possible??


And I know, Drillsideways search retains previous level facets and its
count and it will be achieved by taking dimensions from drilldownQuery. In
my case, "price" is the dimension which was indexed as
numericDocValuesField and added in drilldownQuery. So only it was throwing
an exception when I search through drillsideways search. Am I right or
missed anything?


Kindly help me to solve my issue.

Regards,
Chitra
