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