I read somewhere, we can route specific data on specific shard. And
according to my understanding, we need this feature if we have content with
the different behavior of searches. When we have big documents and more
number of columns to be indexed. In this case, data should be routed on the
machine with high configurations.
I am assuming, i have different capacity machines in cloud and each machine
has one shard. And i want to push more sensitive data on high configuration
