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