• Performing a fuzzy search may retrieve terms with similar spellings: (( te sach nhat ve giai ((co phong) OR (o phong)) minh ) or ( te sach che ve giao li phong tinh ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( te sach nhat ve giai ((co phong) OR (o phong)) minh ) OR ( te sach che ve giao li phong tinh )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( te sach nhat ve giai ((co phong) OR (o phong)) minh ) or ( te sach che ve giao li phong tinh ))".
• Adding a wildcard symbol may retrieve word variants: (( te sach nhat ve giai ((co phong) OR (o phong)) minh ) or ( te sach che ve giao li phong tinh ))*.
