				 * beginning with the search string and the second list contains the
				 * partial matches that start in the middle of the words.
				 * The first list is sorted on count (the number of emails sent to this
				 * email address), name and finally on the email address. This is done
				 * by a natural sort. When this first list already contains the maximum
				 * number of returned items the second list needs no sorting. If it has
				 * less, then the second list is sorted and included in the first list
				 * as well. At the end the final list is sorted on name and email again.
