StatsComponent should support dates (and other non-numeric fields)
------------------------------------------------------------------
Key: SOLR-1023
URL: https://issues.apache.org/jira/browse/SOLR-1023
Project: Solr
Issue Type: New Feature
Affects Versions: 1.4
Environment: Mac OS 10.5, java version "1.5.0_16"
Reporter: Peter Wolanin
Fix For: 1.4
Currently, the StatsComponent only supports single-value numeric fields:
http://wiki.apache.org/solr/StatsComponent
trying to use it with a date field I get an exception like:
java.lang.NumberFormatException: For input string: "2009-01-27T20:04:04Z"
trying to use it with a string I get an error 400 "Stats are valid for single
valued numeric values."
For constructing date facets it would be very useful to be able to get the
minimum and maximum date from a DateField within a set of documents. In
general, it could be useful to get the minimum and maximum from any field type
that can be compared, though that's of less importance.
