: We encountered an issue when using the refine parameter when subfaceting in
: a range facet.
: When enabling the refine option, the counts of the response are the double
: of the counts of the response without refine option.
: We are running Solr 6.6.1 in a cloud setup.
...
: If I execute the same query WITHOUT refine: true in the subfacet, I get the
: following response:
...
: There is a factor 2 difference for each count in each bucket.
:
: If I perform the same queries with a larger range gap, e.g.
: \"start\":0.0,
: \"end\":55000.0,
: \"gap\":5000.0,
: there is no difference between the response with and without refine: true.
FWIW: Based on the info you provided it's impossible for us to tell which
of those 2 responses is "correct" ... ie: you know the source data, and
have access to the index, and can do a test query where you filter (fq) on
those ranges + field values to confirm what the "correct" numFound is --
we can't. So we can't be certain if you're getting the
"correct" counts with or with out the refine param -- which is kind of
important to help troubleshoot.
That said...
: Is this a known issue, or is there something we are overlooking?
: And is there information on whether or not this behavior will be the same
: in Solr 7?
...off the top of my head, I don't know of any specific bugs in 6.x with
type:range facet counts being doubled/halfed when a refined/non-refined
subfacet is used -- but it's certainly possible that one existed and was
explicitly/invidently fixed.
I can tell you that very recently I worked on 2 jiras involving type:range
faceting -- one of which was a bug that caused incorrect results when
"mincount" was used in cloud mode -- and as a result added some more
robust testing (to master and branch_7x) of type:range facets as both
parent facets and sub-facets of type:term facets -- and i did not
encounter any sort of missmatches like the one you are describing...
https://issues.apache.org/jira/browse/SOLR-11824
https://issues.apache.org/jira/browse/SOLR-3218
...if you can reproduce this with branch_7x (7.3) then please file a jira
with some sample data/config/queries that can be used to reproduce.
