• If you are trying to use Boolean operators, they must be ALL CAPS: wing yan ((yuan li) OR (yang li)) ((liu gang) OR (li gang)) pain ((long do) OR (long d)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing yan ((yuan li) or (yang li)) ((liu gang) OR (li gang)) pain ((long do) or (long d)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing yan ((yuan li) or (yang li)) ((liu gang) OR (li gang)) pain ((long do) or (long d)) ;*.
