  === Creating a leader index
  
  Leader indices require a special index setting to ensure that the operations
  that need to be replicated are available when the follower requests them from
  the leader. This setting is used to control how many soft deletes are retained.
  A _soft delete_ occurs whenever a document is deleted or updated. Soft deletes
  can be enabled only on new indices created on or after {es} 6.5.0, and enabled
  by default on new indices created on or after {es} 7.0.0.
