• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu khach)) y sang ma hoi. hieu va cam thu van ((hanh de) OR (hanh kem)) cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu khach)) y sang ma hoi. hieu va cam thu van ((hanh de) OR (hanh kem)) cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu khach)) y sang ma hoi. hieu va cam thu van ((hanh de) OR (hanh kem)) cua triet*".
