• If you are trying to use Boolean operators, they must be ALL CAPS: thu sai ky ((lang mai) OR (((sang tai) OR (tang tai)))) hoi. hieu ve cac xuc va hang tai cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sai ky ((lang mai) or (((sang tai) OR (tang tai)))) hoi. hieu ve cac xuc va hang tai cuu tre*".
