Are there any plans to support a kind of federated search in a future solr version?
I think there are reasons to use seperate indexes for each document type but do combined searches on these indexes (for example if you need separate TFs for each document type). I am aware of http://wiki.apache.org/solr/DistributedSearch and a workaround to do federated search with sharding http://stackoverflow.com/questions/2139030/search-multiple-solr-cores-and-return-one-result-set but this seems to be too much network- and maintenance overhead. Perhaps it is worth a try to use an IndexReaderFactory which returns a lucene MultiReader!? Is the IndexReaderFactory still Experimental? https://issues.apache.org/jira/browse/SOLR-1366 Regards, Kai Gülzau > -----Original Message----- > From: Jonathan Rochkind [mailto:rochk...@jhu.edu] > Sent: Wednesday, June 15, 2011 8:43 PM > To: solr-user@lucene.apache.org > Subject: Re: Multiple indexes > > Next, however, I predict you're going to ask how you do a 'join' or > otherwise query accross both these cores at once though.
