I have a SOLR instance running as a proxy (no data of its own), it just uses
multicore setup where each core has a shards parameter in the search handler.
So my setup looks like this:
solr_proxy/
multicore/
/public - solrconfig.xml has "shards" pointing to some other
SOLR instances with public data
/private - solrconfig.xml has "shards" pointing to some other
SOLR instances with private data
I get the following error during a search if I specify shards parameter in my
request.
I have one core as the default, and then one returns data ok:
http://localhost:8983/solr/select/?q=obama&rows=50
But if I specify as a shard I get this error:
http://localhost:8983/solr/select/?q=obama&rows=50&shards=localhost:8983/solr/public
HTTP ERROR 500
