• If you are trying to use Boolean operators, they must be ALL CAPS: ((((yan liang) OR (you liang))) OR (yang guang)) yuan hui wei yang's ii long do ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((yan liang) OR (you liang))) or (yang guang)) yuan hui wei yang's ii long do ;*".
