• Performing a fuzzy search may retrieve terms with similar spellings: te sai ky tang ma hoi. hieu ((van cam) OR (van lam)) truc ((va hanh) or (va thanh)) vi chua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sai ky tang ma hoi. hieu ((van cam) OR (van lam)) truc ((va hanh) OR (va thanh)) vi chua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sai ky tang ma hoi. hieu ((van cam) OR (van lam)) truc ((va hanh) or (va thanh)) vi chua tre*".
