• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((((dien hinh) OR (tien thinh))) or (diep tinh)) - hanh ban cua dong cong san tuan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((dien hinh) OR (tien thinh))) OR (diep tinh)) - hanh ban cua dong cong san tuan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((dien hinh) OR (tien thinh))) or (diep tinh)) - hanh ban cua dong cong san tuan cau*".
