Kanji lookup resource by "primitive" (not radical)?

Is there some online tool that would allow me to look up all kanji that contain a certain Heisig “primitive” element, even when it is not the radical? For example, I wanted to find all the kanji that have the “guillotine” element in them, on the right hand side. I came up with these in a sort of manual search way:

决, 決, 快, 抉, 缺, 袂, 鴃, 訣.
