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