• Performing a fuzzy search may retrieve terms with similar spellings: ((tu can) or (thuat san)) ky lang van hoe. hieu va ((dau nuoc) OR (cap nuoc)) va thanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((tu can) OR (thuat san)) ky lang van hoe. hieu va ((dau nuoc) OR (cap nuoc)) va thanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((tu can) or (thuat san)) ky lang van hoe. hieu va ((dau nuoc) OR (cap nuoc)) va thanh vai cua tre*".
