• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach lo) or (sach doi)) lang xa hoi. hieu ve cham truc ((va thanh) OR (ban thanh)) vi cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach lo) OR (sach doi)) lang xa hoi. hieu ve cham truc ((va thanh) OR (ban thanh)) vi cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach lo) or (sach doi)) lang xa hoi. hieu ve cham truc ((va thanh) OR (ban thanh)) vi cua tre*".
