How can I guarantee near values ranges of chunks to be in the same shard?

      Given the [example |https://docs.mongodb.com/manual/tutorial/view-sharded-cluster-configuration/]of range partitioning from the official site of MongoDB documentation, we see that the sharding key is based on the zip field. However, having a look at the cluster details, we notice that shard0001 contains two chunks of ranges [1,56000) and [57500,58140). Wouldn't we expect from the intermediate ranges [56000,56800),[56800,57088) and [57088,57500) to be stored also on the shard0001?

      When hearing about range partitioning, I am expecting that every shard should contain continuous shard keys.  Is it possible to achieve that without defining zones?
