• Performing a fuzzy search may retrieve terms with similar spellings: hoc ((cua tinh) OR (ha tinh)) - ((manh trung) or (tmanh trung)) vap nhung cong manh toan cau~.
• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((cua tinh) OR (ha tinh)) - ((manh trung) OR (tmanh trung)) vap nhung cong manh toan cau.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((cua tinh) OR (ha tinh)) - ((manh trung) or (tmanh trung)) vap nhung cong manh toan cau".
• Adding a wildcard symbol may retrieve word variants: hoc ((cua tinh) OR (ha tinh)) - ((manh trung) or (tmanh trung)) vap nhung cong manh toan cau*.
