Yonik Seeley commented on SOLR-939:
-----------------------------------
Right - it made sense to me to go through the FunctionQuery/ValueSource
abstraction to do range filters, as it's a superset of just going off of the
FieldCache (it could work with functions, FileFloatSource, and future payload
or column-stored fields too).
I've been meaning to get back to this patch... at a minimum it would need
support for all of the field types as well as tests. I think I may even have
some local updates since this last patch - I'll have to check.
It would be nice if one could tag a field with info to use
ValueSourceRangeFilter for any range queries... but it doesn't seem necessary
before committing this underlying functionality.
