• If you are trying to use Boolean operators, they must be ALL CAPS: vu san ky tang ((mai hoi) OR (dai hoi)). hieu vu cham ((luc va) OR (duc va)) xanh tai cuc tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu san ky tang ((mai hoi) OR (dai hoi)). hieu vu cham ((luc va) or (duc va)) xanh tai cuc tre*".
