• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach nha me giai ((ca trong) OR (ca thuong)) tin ) OR ( tu cach cua me giai con hong tin ))~.
• Adding a wildcard symbol may retrieve word variants: (( te sach nha me giai ((ca trong) or (ca thuong)) tin ) or ( tu cach cua me giai con hong tin ))*.
