• If you are trying to use Boolean operators, they must be ALL CAPS: cu cao ky nang x hoi. hieu ve ((cham luc) OR (nhan luc)) ((va thanh) OR (va danh)) di cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cu cao ky nang x hoi. hieu ve ((cham luc) OR (nhan luc)) ((va thanh) or (va danh)) di cua tre".
• Adding a wildcard symbol may retrieve word variants: cu cao ky nang x hoi. hieu ve ((cham luc) OR (nhan luc)) ((va thanh) or (va danh)) di cua tre*.
