• Performing a fuzzy search may retrieve terms with similar spellings: te sach ky dang ma hoa. hieu ((van cam) OR (van lam)) xuc va ((thanh vai) or (thanh tai)) cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ky dang ma hoa. hieu ((van cam) OR (van lam)) xuc va ((thanh vai) OR (thanh tai)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ky dang ma hoa. hieu ((van cam) OR (van lam)) xuc va ((thanh vai) or (thanh tai)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te sach ky dang ma hoa. hieu ((van cam) OR (van lam)) xuc va ((thanh vai) or (thanh tai)) cua tre*.
