• Performing a fuzzy search may retrieve terms with similar spellings: su sach y nang ma hoi. hieu ve cam tuc va duong co ((cua te) or (((cua tre) OR (dua tren))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y nang ma hoi. hieu ve cam tuc va duong co ((cua te) OR (((cua tre) OR (dua tren))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y nang ma hoi. hieu ve cam tuc va duong co ((cua te) or (((cua tre) OR (dua tren))))*".
