   Sometimes the failures are specific to a shard replica. The copies that failed
   will not be eligible for fast recovery but those that succeeded still will be.
   This case is reported as follows:
   
  -[source,js]
  +[source,console-result]

   {
      "_shards": {

  // TEST[setup:twitter]

negative.code: --------------------------------------------------
  POST /_flush/synced
  --------------------------------------------------
  // TEST[skip: Synced flush can conflict with scheduled flushes in doc tests]
  
  The response contains details about how many shards were successfully
  sync-flushed and information about any failure.
