Tomás Fernández Löbbe updated SOLR-11043:
-----------------------------------------
Attachment: SOLR-11043.patch
Here is a patch with some more tests. The random test fails for some seeds with
point fields. I suspect it may be a bug with point fields. Will look into that
> Negative single-valued float field values are not included in facet range
> counts when the field has docvalues and facet.range.method=dv

> Found while increasing TestPointsField randomization on SOLR-10796:
> When a non-multiValued float field, either Trie- or points-based, has
> docvalues and a facet.range request uses {{facet.range.method=dv}}, negative
> values are not included in the facet range counts.
> This test added to SimpleFacetsTest succeeds for the request with
> {{facet.range.method=filter}}, but fails for the same request with
> {{facet.range.method=dv}} (failure is on line 17 in the listing below) - see
> the schema excerpt below for field/type:
> {code:java}
> 1: public void testDvMethodNegativeFloatRangeFacet() throws Exception {
