• If you are trying to use Boolean operators, they must be ALL CAPS: su xac ky tang ma hoi. hieu ve cam ((duc ban) OR (dua ban)) thanh ((san cua) OR (dan cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su xac ky tang ma hoi. hieu ve cam ((duc ban) or (dua ban)) thanh ((san cua) OR (dan cua)) triet".
