From wwwopac.ashx version 3.7.15132.1, results from facet searching will automatically be sorted on hits count. Sorting will be descending, so, from the list of found facets, the term with the highest count will end up on top of the list, the term with the second highest count will be second on the list, etc. Only when some terms appear the same number of times in the searched records, these specific terms will be sorted alphabetically within the larger sorting on hits count. The automatic sorting on hits count for faceted searching cannot be switched off.
