After finding a list of search results, allow user to select the results and command-option-drag them to another folder (or the stack) to create aliases or control-drag to create symlinks. I can't find anywhere in the documentation whether control-dragging a file/folder currently creates a symlink or is just duplicate functionality of command-option-drag. Either way, you get the idea. This functionality is allowed in the Finder from a Spotlight search results window.
