Yes Joel, that would be very welcome indeed. We already add up statistics returned by custom
collectors in the QueryComponent. With the current patch this is still an issue for us. I'd
love to implement an interface and provide a Map<String, Float> getStats() method which
would then be summed up.

The most relevant use case for us is that we do online result deduplication, but still need
the total number for numRows without deduplication as well ass the real number of (deduplicated)
results.

> This issue is to add configurable custom collectors to Solr. This expands the design
and work done in issue SOLR-1680 to include:
> 1) CollectorFactory configuration in solconfig.xml
> 2) Http parameters to allow clients to dynamically select a CollectorFactory and construct
a custom Collector.
> 3) Make aspects of QueryComponent pluggable so that the output from distributed search
can conform with custom collectors at the shard level.
