• Performing a fuzzy search may retrieve terms with similar spellings: te sach ((y nang) OR (ly nang)) ((ma hoi) or (ma hoa)). hieu ve cac lo ban hanh vai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ((y nang) OR (ly nang)) ((ma hoi) OR (ma hoa)). hieu ve cac lo ban hanh vai cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ((y nang) OR (ly nang)) ((ma hoi) or (ma hoa)). hieu ve cac lo ban hanh vai cua tre*".
