  -The response to a bulk action is a large JSON structure with 
  -the individual results of each action performed, 
  -in the same order as the actions that appeared in the request. 
  -The failure of a single action does not affect the remaining actions.
  -
   There is no "correct" number of actions to perform in a single bulk request. 
   Experiment with different settings to find the optimal size for your particular workload.

  ===== Partial responses
  To ensure fast responses, the bulk API will respond with partial results if one or more shards fail. 
  See <<shard-failures, Shard failures>> for more information.
