hoc thieu » toc thieu, hoc hien
ho chieu » theo chieu, doi chieu, mot chieu
van toan » van tuan, van tan, van thanh

• Performing a fuzzy search may retrieve terms with similar spellings: ((ho chieu) or (hoc thieu)) sang - hanh truong cao ((hung trong) OR (dung trong)) van toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((ho chieu) OR (hoc thieu)) sang - hanh truong cao ((hung trong) OR (dung trong)) van toan cau*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((ho chieu) or (hoc thieu)) sang - hanh truong cao ((hung trong) OR (dung trong)) van toan cau*".
