Hi Tom,
I believe Solr will automatically use DocValues for faceting if you've
defined them in the schema.

Thanks Otis,
I'm looking forward to the presentation videos.
I'll look into using DocValues.Re-indexing 200 million docs will take a
while though :).
Will Solr automatically use DocValues for faceting if you have DocValues
for the field or is there some configuration or parameter that needs
Hi Tom,
Check http://blog.sematext.com/2013/11/09/presentation-solr-for-analytics/

shows lower heap usage, which means you'll get further without getting
this OOM. In our experiments we didn't sort, facet, or group, and I

Hi Yonik,
I don't know enough about JVM tuning and monitoring to do this in a clean
way, so I just tried setting the max heap at 8GB and then 6GB to force

We are considering indexing our 11 million books at a page level, which
comes to about 3 billion Solr documents.
Our subject field by necessity is multi-valued so the UnInvertedField is
used for faceting.
