Hi Bruno,

I just tested this scenario in my local solr 5.3.1 and it returned results
from two identical collections. I doubt if it is broken in 5.4 just double
check if you are not missing anything else.

Thanks,
Susheel

http://localhost:8983/solr/c1/select?q=id_type%3Ahello&wt=json&indent=true&collection=c1,c2

responseHeader": {"status": 0,"QTime": 98,"params": {"q": "id_type:hello","
indent": "true","collection": "c1,c2","wt": "json"}},
response": {"numFound": 2,"start": 0,"maxScore": 1,"docs": [{"id": "1","
id_type": "hello","_version_": 1522623395043213300},{"id": "3","id_type": "
hello","_version_": 1522623422397415400}]}
