You can also make a copy of your existing index, bring it up as a second instance/core and then send delete queries to both indexes.

You have a couple of choices here: 1> Just reindex everything from scratch into two shards 2> delete all the docs from your index that will go into shard 2 and 2> just index the docs for shard 2 in your new shard But I want to be sure you're on the right track here. You only need to shard if your index contains "too many" documents for your hardware to produce decent query rates. If you are getting (and I'm picking this number out of thin air) 50 QPS on your hardware (i.e. you're not stressing memory etc) and just want to get to 150 QPS, use replication rather than sharding. see: http://wiki.apache.org/solr/SolrReplication Best Erick On Fri, May 4, 2012 at 9:44 AM, michaelsever <sever_mich...@bah.com> wrote: > If I have a single Solr index running on a Core, can I split it or > migrate it into 2 shards? > > -- > View this message in context: > http://lucene.472066.n3.nabble.com/Single-Index-to-Shards-tp3962380.ht > ml Sent from the Solr - User mailing list archive at Nabble.com.
