---------------------------------------------
bq. Is it possible that the same shard key spans multiple shards?
Yes. By using the bitSeparator syntax for composite keys, a single shard key
can span multiple shards.

why is this an array
{"a!":[]}
? will there be multiple rules for the same shard key ?
{quote}
Yes there can be multiple rules for the same key because the ranges may span
multiple target shards.

> Enable SolrCloud users to split out a set of documents from a source
> collection into another collection.
