• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach thi thi thanh pho tu thong ) OR ( ((su sach) OR (so sach)) tri te hang hoa he thong ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach thi thi thanh pho tu thong ) or ( ((su sach) OR (so sach)) tri te hang hoa he thong ))~".
• Adding a wildcard symbol may retrieve word variants: (( te sach thi thi thanh pho tu thong ) or ( ((su sach) OR (so sach)) tri te hang hoa he thong ))*.
