Search
category names it, totalResults counts that category’s matches and categories lists the other matching categories with their counts and links. To search one of them, pass its link as url. A keyword that leads to a department page (subcategory tiles, no products) is answered from the subcategory holding the product line that matches it most often; totalAcrossCategories then counts the whole department. There is no paging: only the first result rows come back. Each search is billed as one request.
