• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((trieu tinh) or (cua tinh)) - ((hanh trung) OR (manh trung)) tuan dung muong thanh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((trieu tinh) OR (cua tinh)) - ((hanh trung) OR (manh trung)) tuan dung muong thanh toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((trieu tinh) or (cua tinh)) - ((hanh trung) OR (manh trung)) tuan dung muong thanh toan cau*".
