RE: Clarity on Sharding Concepts.
Both. One shard will have roughly half the documents, and the indices built from them; the other shard will have the other half of the documents, and the indices built from those. There won't be one location that contains all the documents, nor all the indices. -Original Message- From: Siddhartha Singh Sandhu [mailto:sandhus...@gmail.com] Sent: Tuesday, May 31, 2016 10:43 AM To: solr-user@lucene.apache.org; muge...@gmail.com Subject: Re: Clarity on Sharding Concepts. Hi Mugeesh, I was speculating whether sharding is done on: 1. index terms with each shard having the whole document space. 2. document space with each shard have num(documents/no. of shards) of the documents divided between them.

Re: Clarity on Sharding Concepts.
Hi, To read out this document https://cwiki.apache.org/confluence/display/solr/Shards+and+Indexing+Data+in+SolrCloud for proper understanding. FYI, you are using implicit router, a document will be divided randomly based on hashing technique. If you indexed 50 documents, it will be divided into 2 parts, 1 goes to shard1, second one is shard2 and same document will be go their replica respectively .

Clarity on Sharding Concepts.
Hi Community, I need some help understanding some concepts. I have the config on 2 severs: 2 shards each with 1 replica. Hence, on each server I have 1. shard1_replica1 2 . shard2_replica1 Suppose I have 50 documents then, shard1_replica1 + shard2_replica1 = 50 ? or shard2_replica1 = 50 && shard1_replica1 = 50 ? Regards, Sid.
