parsing of date ranges in queries no longer consults the index mapping. it was deteremined that this wasn't very useful and led to overly complicated query syntax/behavior. instead, applications get set the datetime parser used for date range queries with the top-level config QueryDateTimeParser also, we now support querying date ranges in the query string, the syntax is: field:>"date" >,>=,<,<= operators are supported the date must be surrounded by quotes and must parse in the configured date format
