• If you are trying to use Boolean operators, they must be ALL CAPS: thuat san ky ((nang xa) OR (lang xa)) hoi. hieu va chat xuc van anh va ((dung tren) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat san ky ((nang xa) OR (lang xa)) hoi. hieu va chat xuc van anh va ((dung tren) or (cua te))*".
