bq: But when indexing a document in one shard,it gets reflected in every shard of that collection
This is a misunderstanding (and I'm being a bit pedantic here). Each shard contains a portion of the entire corpus. Say you have 1M docs and 2 shards. Each shard will have very close to 500K documents. If a shard has multiple _replicas_, each replica has a copy of the doc. Please take the time to work through the Solr tutorials, much will become clearer. You don't need any kind of extensive setup, you can see how things run on any machine you have.
