 for each term returned by the aggregation which represents the 'worst case' error in the document count and can be useful when
 deciding on a value for the `shard_size` parameter. This is calculated by summing the document counts for the last term returned
 by all shards which did not return the term. In the example above the error in the document count for Product C would be 15 as

+Shard B was the only shard not to return the term and the document count of the last term it did return was 15. The actual document
 count of Product C was 54 so the document count was only actually off by 4 even though the worst case was that it would be off by
 15.  Product A, however has an error of 0 for its document count, since every shard returned it we can be confident that the count
 returned is accurate.
