When a local search is preferred allow for it to be done by passing in a 'only_direct' option, also allows passing in a 'include_self' option to ignore/include the current node when finding. The defaults of 'include_self' and 'only_direct' work just as they did prior to this change, so that the addition does not affect current usage(s) of this method.
