Can Solr query join on multiple fields? Or, anyway to achieve equivalent
function with current join syntax?
From the Solr Wiki and examples found on the web, the syntax only supports join
on one field from a doc to another field of other docs, like below:
{!join from=customer_name to=name}stat

Hi,
We were trying to merge a large index (9GB, 21 million docs) into current index
(only 13MB), using mergeindexes command ofCoreAdminHandler, but always run into
OOM error. We currently set the max heap size to 4GB for the Solr server. We
are using 4.6.0, and did not change the original solrc
