  Request results are returned on a best-effort basis. If you specify <code>MaxResults</code> in the request, the
  response includes information up to the limit specified. The number of items returned, however, can be between
  zero and the value of <code>MaxResults</code>. If the service reaches an internal limit while processing the
  results, it stops the operation and returns the matching values up to that point and a <code>NextToken</code>.
  You can specify the <code>NextToken</code> in a subsequent call to get the next set of results.
