When searching for collections, all collections may be presented as potential search results, regardless of whether these are included in other collections.
As shown in the example, the "subfolder1" collection is displayed along with other collections. The "Number of ancestors" metadata field is displayed in the preview window. The value indicates how many collection levels exist above the selected collection. Inversely, the "Number of children" value indicates how many items are included within that collection.
Collection Hierarchy and Deletion
Please note that deleting a collection, which contains another collection, will not delete sub-collections.
Please note that deleting a collection does not delete the items in the collection.
