Subject RE: Does lucene support distributed indexing?
Date Mon, 28 Apr 2008 18:53:02 GMT
Solr does not do distributed indexing, but the development version _does_ do distributed search,
in addition to replication. Currently, you can manually shard up your data to a set of Solr
instances, and then query them by adding a 'shard=localhost:8080/solr_1,localhost:8080/solr_2'
parameter.

See https://issues.apache.org/jira/browse/SOLR-303

Thanks,
Stu

Solr does not do distributed indexing, but index replication. All copies are identical.
Lucene has some build in support for distributed search, please take a look at RemoteSearchable.
For indexing, you can add a front load balancer in a naïve way.
