Searching on multiple cores using MultiSearcher

["Zhang, Lisheng" <Li...@BroadVision.com>]

Hi,
 
At lucene level we have MultiSearcher to search a few cores at the same time with same query,
at solr level can we perform such search (if using same config/schema)? Here I donot mean to
search across shards of the same collection but independent collections?
 
Thanks very much for helps, Lisheng
