• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((cac ky) OR (sai ky)) nang xa hoi. thi van thai tuc va hang dau ((cua tre) OR (cua te))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((cac ky) or (sai ky)) nang xa hoi. thi van thai tuc va hang dau ((cua tre) OR (cua te))*".
