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