I want to get the value of the shard ID/Name for a given routing string. Say I got two shards data-1 and data-2 and routing string route1. How can I simply calculate which shard ID/Name will be the result if the ES 2 routing algorithm?

How to calculate the shard id/name for given routing string?

The documentation I linked above has the formula for computing the id of the targeted shard. However when talking about security you might want to check out https://www.elastic.co/guide/en/shield/current/index.html
