bq: Not sure what the issue was, in previous versions of Solr, clicking reload
would send a commit to all replicas, right
Reloading doesn't really have anything to do with commits. Reload
would certainly
cause a new searcher to be opened and thus would pick up any changes
that hat been hard-committed (openSearcher=false), but that's a complete
side-effect. Simply issuing a commit on the url to the _collection_ will cause
commits to happen on all replicas, as:
blah/solr/collection/update?commit=true
