-       returned, the default sort for the study list is dictated by the image archive that hosts these studies for the viewer and study list sorting will be disabled. If there are less than or equal to 100 studies returned, they will be sorted by study date (most recent to oldest) and study list sorting will be enabled. Whenever a query returns greater than 100 studies, use filters to narrow results below 100 studies to enable Study List sorting.
