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