• Performing a fuzzy search may retrieve terms with similar spellings: (( tu sach ha ke gia ba thong tin ) or ( nuoc sach cca moi ((gioi tam) OR (gioi cam)) thuong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach ha ke gia ba thong tin ) OR ( nuoc sach cca moi ((gioi tam) OR (gioi cam)) thuong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach ha ke gia ba thong tin ) or ( nuoc sach cca moi ((gioi tam) OR (gioi cam)) thuong tin ))".
