• Performing a fuzzy search may retrieve terms with similar spellings: so sach ty ((xang cai) OR (cang chai)) hoi. thien van lam ((tuc va) or (loc va)) canh dan cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: so sach ty ((xang cai) OR (cang chai)) hoi. thien van lam ((tuc va) OR (loc va)) canh dan cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "so sach ty ((xang cai) OR (cang chai)) hoi. thien van lam ((tuc va) or (loc va)) canh dan cua tre".
