Subject [jira] [Updated] (SOLR-1023) StatsComponent should support dates (and other non-numeric fields)
Date Wed, 19 Oct 2011 17:45:10 GMT

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

Gunnlaugur Thor Briem updated SOLR-1023:
----------------------------------------

    Attachment: SOLR-1032-against-lucene_3_4_0.patch

Updated, fixed and cleaned-up patch against 3.4.0 (applies cleanly against branch_3x and trunk
as well). All tests pass. Can we get this in? :)

> 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.
