• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y lang xa hoi. ((((hieu van) OR (hieu ve))) or (lieu va)) cau phuc va thanh di cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y lang xa hoi. ((((hieu van) OR (hieu ve))) OR (lieu va)) cau phuc va thanh di cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y lang xa hoi. ((((hieu van) OR (hieu ve))) or (lieu va)) cau phuc va thanh di cua triet*".
