Hello -
I’m not sure If this is an appropriate use for Solr, but I want to stay away 
from a typical DB store for high availability reasons.

I am storing documents that may have a common value for a field we’ll call 
“category”.
In another field there will be an integer field we’ll call “rating”.

I would like to group the documents on the “category” field and display the 
average “rating” per group.

The stats component lets me get the avg rating, but when I collapse the results 
into groups it gives me the average for the entire collection, rather than for 
the specific group.

Am I going about this wrong?
Is it possible to get the desired outcome with a  single query?

I’d appreciate any insight!
Thank you,
