Sorry for the basic question
q=*:*&fq=-sku:2471834&fq=FiltroDispo:1&fq=has_image:1&rows=100&fl=descCat3,IDCat3,ranking2&group=true&group.field=IDCat3&group.sort=ranking2+desc&group.ngroups=true
returns some groups with no results. I'm using solr 4.8.0, the collection
has 3 shards
Am I missing some parameters?
<lst name="grouped">
<lst name="IDCat3">
<int name="matches">297254</int>
<int name="ngroups">49</int>
<arr name="groups">
<lst>
<int name="groupValue">0</int><result name="doclist"
numFound="0" start="0"/></lst>
...
<lst><int name="groupValue">12043</int><result name="doclist"
numFound="2" start="0"><doc><int name="IDCat3">12043</int><str
name="descCat3">SSD</str><int name="ranking2">498</int></doc></result></lst>
