• If you are trying to use Boolean operators, they must be ALL CAPS: te cac ((ky lang) OR (ky tang)) xa hoi. thien van pham duc ban thanh hoi ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te cac ((ky lang) OR (ky tang)) xa hoi. thien van pham duc ban thanh hoi ((cua tre) or (cua te))*".
