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