Nicholas Jakobsen commented on SOLR-3652:
-----------------------------------------
I have a more generic DSL that I use to specify fields for faceting. For
simplicity, all the values from range facets (including dates, datetimes,
integers, floats, doubles, etc...) are converted to a float for indexing. This
is why I haven't explored other data types.
As for SOLR-2773, Ha! The amount of time I've spent dealing with BCE to
signed-year conversions, gregorian calendars, and far past dates. Jumping into
the conversation in SOLR-1899 is a little confusing. Why don't you email me and
explain the issue, and I'll see if I can help.
