Hi all, Let’s say I have an index of books, similar to the example in the facet demo [1] with a hierarchical facet field encapsulating `Genre / Author’s nationality / Author’s name`.
I might like to find the latest publish date of a book written by Mark Twain, the sum of the prices of books written by American authors, and the number of sci-fi novels. As far as I understand, this would require faceting 3 times over the match-set, one iteration for each aggregation of a different type (max(date), sum(price), count). That seems inefficient if we could instead compute all aggregations in one pass. Is there a way to do that?
