Calls that use CategoryHistogramContainer:
Statistical (item count) information on the categories that contain items that match the search criteria or specified category or categories. A category histogram contains information for up to 10 child categories. Search result total entries may not necessarily match the sum of category histogram item counts.
For search calls, the item count shows the distribution of matching items across each of the returned categories. A category histogram is not returned if there are no matching items or if the search is restricted to a single leaf category.
For getHistograms, the category histogram contains the total item count for the specified category and item counts for the child categories containing the most item listings. A category histogram is not returned if the specified category is a leaf category.
For categories associated with specific items, review the individual item containers returned in the search result.
