DAT One has a feature to help you out if you are not finding the number of results you were expecting.  To see even more matches that may help you, enable the Include Similar Results option on your search.

Similar matches do not quite match your original search criteria.  These results may be listed for a different day, may be further away, or possibly older than your original search.

Note:  You can see up to 1000 similar results when the feature is enabled.
