However, you can query Solr remotely, if that's what you mean, for example using SolrJ if your application is written in Java. > 2.

Yes, please look for "DistributedSearch" on the Wiki. > 3. consider a case: > i have indexes in 2 shards, and i merge the indexes (present in 2 > shards) onto the 3rd shard > now i add more documents into shard1 and delete some documents > from shard 2 and update the indexes. > is it possible to send the differences only into shard 3 and then > merge it at shard 3? If I understood you correctly, then no, sending only the newly added/deleted documents in 2 indices to the 3rd index after the fact is not doable.
