Subject [jira] Updated: (SOLR-1023) StatsComponent should support dates (and other non-numeric fields)
Date Thu, 21 May 2009 07:28:45 GMT

     [ https://issues.apache.org/jira/browse/SOLR-1023?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Shalin Shekhar Mangar updated SOLR-1023:
----------------------------------------

    Description: 
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.

Marking for 1.5 because although it is useful, there is no patch yet.
