Hi Stu,

You can simply take your N Lucene indices managed by your N Solr instances and merge them
into 1 Lucene index.  Then you can take your N Solr schema.xml's and solrconfig.xml's and
merge them into a single schema.xml and a single solrconfig.xml that act as a union of the
previous N configs.  Point your Solr to a newly merged index and use the newly merged configs,
and I think you should be all set.

Is using Solr for email search?

Subject: Merging Solr Collections


I'm considering using embedded Solr in a distributed manner, such that an intermediate result
will be N separate Solr indexes which would then be merged to a single final index.

I know that Lucene can merge indexes ([])
), but I also know that there is more to a Solr Collection than the index.

Does anyone have any suggestions for merging Solr Collections? Or should I forget this plan
of attack...
