• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((mang xa) or (nang x)) hoi. hieu va cao xuc va thanh ve ((cua tre) OR (cua te))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((mang xa) OR (nang x)) hoi. hieu va cao xuc va thanh ve ((cua tre) OR (cua te)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((mang xa) or (nang x)) hoi. hieu va cao xuc va thanh ve ((cua tre) OR (cua te))".
