Ryan McKinley updated SOLR-680:
-------------------------------

    Attachment: SOLR-680.patch

updated:
 * calculate stddev in first pass -- and works distributed (thanks Sean!)
 * throws a full error when asking for a bad field -- this seems better then catching \
                it and adding it to the response.  
 * changed param "stddev" to "twopass" -- now it is a flag to calculate things that \
require a 2nd pass through the data.  Currently only "median"

I'd like to commit this soon...

> StatsComponent - it returns min,max,sum,qt,avg of specified number fields:
> request parameters:
> &stats=on&stats.field=price
> {code:xml}
> <stats>
> <stats_fields>
> <lst name="price">
> <double name="min">10</double>
> <double name="max">30</double>
> <double name="avg">20</double>
> <double name="sum">60</double>
> <double name="qt">3</double>
> </lst>
> </stats_fields>
> </stats>
> {code}
> WRT "stats", the component can output sum and avg, but not sd and var.
> USE CASE:
> StatsComponent can be used to get "market price" of DocSet e.g. rental housing \
> site, package tour site.
