Thanks Otis,
So Lucene's functions for merging indexes will correctly merge Solr Collections, without losing stored data? Thats good news! Webmail.us is currently using vanilla Lucene for indexing our customer e-mail, which is working just fine. But our Log Search implementation isn't scalable enough to handle our growth, so I've been charged with finding a better solution for keeping track of the 60GB+ of log data we generate daily. Solr is definitely being considered. Thanks!

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 Webmail.us using Solr for email search?

I know that Lucene can merge indexes ( http://lucene.zones.apache.org:8080/hudson/job/Lucene-Nightly/javadoc/org/apache/lucene/index/IndexWriter.html#addIndexes(org.apache.lucene.store.Directory[]) ), 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... Thanks, Stu Hood Webmail.us "You manage your business. We'll manage your email."®
