Shai Erera commented on LUCENE-4748:
------------------------------------

Thanks for all the answers Mike!

The fixes look. And I suggest that all the nocommits that are optimizations should be converted
to TODOs. We should get this feature in, optimize later.

> This came out of a discussion on the java-user list with subject
> "Faceted search in OR": http://markmail.org/thread/jmnq6z2x7ayzci5k
> The basic idea is to count "near misses" during collection, ie
> documents that matched the main query and also all except one of the
> drill down filters.
> Drill sideways makes for a very nice faceted search UI because you
> don't "lose" the facet counts after drilling in.  Eg maybe you do a
> search for "cameras", and you see facets for the manufacturer, so you
> drill into "Nikon".
> With drill sideways, even after drilling down, you'll still get the
> counts for all the other brands, where each count tells you how many
> hits you'd get if you changed to a different manufacturer.
> This becomes more fun if you add further drill-downs, eg maybe I next drill
> down into Resolution=10 megapixels", and then I can see how many 10
> megapixel cameras all other manufacturers, and what other resolutions
> Nikon cameras offer.
