• Performing a fuzzy search may retrieve terms with similar spellings: vu khach ty tang ma hoa. hieu vu cham duc ((((va hanh) OR (van hanh))) or (va thanh)) lam cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu khach ty tang ma hoa. hieu vu cham duc ((((va hanh) OR (van hanh))) OR (va thanh)) lam cuu tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khach ty tang ma hoa. hieu vu cham duc ((((va hanh) OR (van hanh))) or (va thanh)) lam cuu tre*".
