• Performing a fuzzy search may retrieve terms with similar spellings: su sach o lang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) chat huu va danh va cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach o lang xa hoi. ((((hieu ve) OR (hieu van))) OR (hieu va)) chat huu va danh va cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach o lang xa hoi. ((((hieu ve) OR (hieu van))) or (hieu va)) chat huu va danh va cua te*".
