• Performing a fuzzy search may retrieve terms with similar spellings: su sach ((ty hang) or (ty xang)) ma hoi. hieu va cham ((xuc gia) OR (luc gia)) thanh le cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ((ty hang) OR (ty xang)) ma hoi. hieu va cham ((xuc gia) OR (luc gia)) thanh le cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ((ty hang) or (ty xang)) ma hoi. hieu va cham ((xuc gia) OR (luc gia)) thanh le cua tre".
• Adding a wildcard symbol may retrieve word variants: su sach ((ty hang) or (ty xang)) ma hoi. hieu va cham ((xuc gia) OR (luc gia)) thanh le cua tre*.
