• Performing a fuzzy search may retrieve terms with similar spellings: su sac ((ky dang) or (ky danh)) ha noi. thien van cham ((luc van) OR (luu van)) hanh vi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sac ((ky dang) OR (ky danh)) ha noi. thien van cham ((luc van) OR (luu van)) hanh vi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sac ((ky dang) or (ky danh)) ha noi. thien van cham ((luc van) OR (luu van)) hanh vi cua tu".
• Adding a wildcard symbol may retrieve word variants: su sac ((ky dang) or (ky danh)) ha noi. thien van cham ((luc van) OR (luu van)) hanh vi cua tu*.
