I'm using Solr 4.10.1 and FieldCollapsing but when adding expand=true
and activating ExpandComponent the expanded section into result contains
only one group head and not all group heads present into the result.
I don't know if this is the intended behaviour. Using a query q=*:* the
expanded section increase the number of group heads but not all 10 heads
group are present. Also removing max= parameter on !collapse makes
display couple of more heads but not all .
Regards
Example of response with only one group head into expanded but 10 are
returned.
