• If you are trying to use Boolean operators, they must be ALL CAPS: nina sun ((can run) OR (yan kun)) wang yan di ((((how seo) OR (how so))) OR (how self)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "nina sun ((can run) or (yan kun)) wang yan di ((((how seo) OR (how so))) or (how self)) ;~".
• Adding a wildcard symbol may retrieve word variants: nina sun ((can run) or (yan kun)) wang yan di ((((how seo) OR (how so))) or (how self)) ;*.
