Please add a "Contains" as a new filter in the Keyword Ideas section of the Keyword explorer. For many other languages than English, there are many compounded words. But these do not show up anywhere in the keyword ideas list. Because this list assumes that each word is a separate entity. Like "Excel training". However, in many other languages this would be written as "Exceltraining". So, there are huge keyword opportunities missing in these lists, at least in my language (Swedish).
