• Performing a fuzzy search may retrieve terms with similar spellings: (( thuoc sach nha me bai hoc thong tin ) or ( su sach ((phat ve) OR (phat vi)) gioi co huong tin ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( thuoc sach nha me bai hoc thong tin ) OR ( su sach ((phat ve) OR (phat vi)) gioi co huong tin )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( thuoc sach nha me bai hoc thong tin ) or ( su sach ((phat ve) OR (phat vi)) gioi co huong tin ))".
• Adding a wildcard symbol may retrieve word variants: (( thuoc sach nha me bai hoc thong tin ) or ( su sach ((phat ve) OR (phat vi)) gioi co huong tin ))*.
