• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky sang ma hoi. hieu va ((cam luc) OR (cau luc)) va danh di ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky sang ma hoi. hieu va ((cam luc) OR (cau luc)) va danh di ((cua tre) or (cuu tre))".
