Gunnlaugur Thor Briem commented on SOLR-1023:
---------------------------------------------
No, pretty similar.
In my two patches the only difference was that the trunk version used
{{BytesRef}}s where the branch_3x one used {{String}}s.
Here are the changes Ryan made from my trunk patch:
(a) started passing around {{SchemaField}}s rather than {{FieldType}}s, I think
specifically in order to call {{ft.toObject(sf, value)}} in
{{StatsValuesFactory}}. But that {{toObject}} method isn't available in
{{branch_3x}} as he pointed out, so the whole {{FieldType}}-to-{{SchemaField}}
change is probably not needed there. Much of the diff stems from this.
(b) generalized {{class DoubleStatsValues extends AbstractStatsValues<Double>}}
to {{class NumericStatsValues extends AbstractStatsValues<Number>}}
(c) made {{DateStatsValues}} extend {{AbstractStatsValues<Date>}} instead of
{{AbstractStatsValues<String>}} (as it should), with the simplifications that
allowed.
(d) fixed some indentation bloopers from me.
I've updated my branch_3x SVN patch with changes (b), (c) and (d), attaching.

> 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.
