Here here. I'm still just using results.each_with_groupby_and_count
to essentially hand-build my facets, because we need facets to be
based on all results in the DB, not just the current page. I'm not
sure I can ever recall having seen a search where facets were supposed
to be relative to the current page. I believe the "point" of facets
(at least as I've seen them used, on eBay, Yelp, etc) is to give the
user a sense of all the results returned, so the user can know which
additional filters they might want to apply to their search.
Until the Powers that Be see fit to revise facets to incorporate all
results, you can always try something like:
categories_hash = {}
categories = Item.search(search_string, :group_by =>
'category_ids', :group_function => :attr, :group_clause => "@count
DESC")
categories.each_with_groupby_and_count { |item, group, count|
categories_hash.merge!(group => count) }
We use the above to build that incorporates results grouped by
category_id across all 2 million items in our DB. Its uglier than
facets, but it doesn't consider pagination.
Cheers,
Bill
