I have facets that are hierarchical. For example, Location can be represented
as this hierarchy:
Country > State > City
If each document can only have a single value for each of these facets, then I
can just use separate fields for each facet.
But if multiple values are allowed, then that approach would not work. For
example if a document has 2 Location values:
US>CA>San Francisco
US>MA>Boston
If I just put the values "CA" & "MA" in the field "State", and "San Francisco"
& "Boston" in "City", facetting would not work. Someone could select "CA" and
the value "Boston" would be displayed for the field "City".
How do I handle this use case?
Thanks
