Hi folks, I think I'm missing something fundamental about how subfacets work and relate to each other. I don't really understand when it's legal to reference a subfacet, and when it's not.
For example, here's a simple subfacet example from http://yonik.com/solr-subfacets/ top_authors:{ type: terms, field: author, limit: 7, sort: "revenue desc", facet:{ revenue: "sum(sales)" } } Notice how "revenue" is referenced from top_authors.sort? The thing is, I haven't seen any examples where the subfacet is referenced *except* for sort. What I'm actually trying to accomplish is doing some post-processing with the aggregation functions. But I don't want to aggregate at the "leaf buckets" -- I'm trying to aggregate *across* buckets at a higher level. You could think of this as similar to the "reduce" phase of a map-reduce. In other words, I know how to fan *out* with subfacets to create more buckets; what I don't know is how to then reduce those buckets into aggregate statistics about the buckets. What am I missing? Thanks! Scott
