Subject [jira] [Updated] (LUCENE-4885) each FacetResult should return the facet equivalent of totalHits
Date Sun, 07 Apr 2013 12:45:18 GMT

Michael McCandless updated LUCENE-4885:
---------------------------------------

    Attachment: LUCENE-4885.patch

New patch, moving the count to FacetResultNode.

I'm sure it's possible to get this count for the TopKInEach case but I don't understand the
code well enough so it's -1 for now.

Also ... I'm not sure this count really belongs in the FRN: it seems quite wasteful in the
common case of single root and lots of children to have this unused int on each child node.
 Or I guess the issue is that we don't have a separate class for the "leaf" vs for intermediate
nodes.  I guess the wasted int doesn't usually matter, since you usually don't request too
many children, and these classes are transient ...

> This is cheap to compute, since the TopKFRH already must visit all non-zero-count ords
under the FacetRequest.categoryPath.
> This can be useful to a front end, eg to know whether to present a "More..." under that
dimension or not, whether to use a suggester like LinkedIn's facet UI, etc.
