• Performing a fuzzy search may retrieve terms with similar spellings: su sach tu nong va hoi. lieu va dau ((tuc van) or (truc van)) hanh ((di cuu) OR (di cau)) tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu nong va hoi. lieu va dau ((tuc van) OR (truc van)) hanh ((di cuu) OR (di cau)) tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu nong va hoi. lieu va dau ((tuc van) or (truc van)) hanh ((di cuu) OR (di cau)) tre*".
