Sum and Average for Facet Search
Brand New feature not seen anywhere else!
Normally when you do a facet search, you get how many hits for that facet. This is a great feature. But there is more!
Now wiht 2.1.6 beta, you can also get Sum and Average for a different field!
It's just like SQL:
select count(*), sum(f2),avg(f2) from t group by f1
