• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((thue hang) OR (thue thanh)) x hoi. hieu ve cham hoc ban anh de ((cua triet) or (cua cu))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((thue hang) OR (thue thanh)) x hoi. hieu ve cham hoc ban anh de ((cua triet) OR (cua cu))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((thue hang) OR (thue thanh)) x hoi. hieu ve cham hoc ban anh de ((cua triet) or (cua cu))*".
