• Performing a fuzzy search may retrieve terms with similar spellings: ((thu cach) OR (tu cach)) tu sang ma hoi. hieu van ((cam loc) or (cam lo)) va danh via cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu cach) OR (tu cach)) tu sang ma hoi. hieu van ((cam loc) OR (cam lo)) va danh via cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu cach) OR (tu cach)) tu sang ma hoi. hieu van ((cam loc) or (cam lo)) va danh via cua triet*".
