Hi all,

Newbie question: trying to use Elastic Search as NoSql analytics tool (not  
for text search). My understanding is that for more than one shard the  
accuracy of counts and aggregations is an approximation? What if I'm using  
exact term matching (text analysis turned off) and doing histogram  
aggregations, will these be approximations in a cluster as well?

Would need some kind of pointer on this, bit in the dark on this. Currently  
reading up on accuracy in the Elastic Search guide. I could set up routing  
to specific shards to avoid this, but seems like an advanced topic.

Thank you in advance, Chris
