 A frozen index has almost no overhead on the cluster (except
 for maintaining its metadata in memory), and is blocked for write operations.
 See <<frozen-indices>> and <<unfreeze-index-api>>.

+limitation might be removed in the future.

 When a frozen index is unfrozen, the index goes through the normal recovery 
 process and becomes writeable again. See <<frozen-indices>> and <<freeze-index-api>>.
