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