• Performing a fuzzy search may retrieve terms with similar spellings: vu dai ((ky tang) OR (ky nang)) van hoc. hieu ve cam xuc ((va dang) or (hoa lang)) de cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu dai ((ky tang) OR (ky nang)) van hoc. hieu ve cam xuc ((va dang) OR (hoa lang)) de cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu dai ((ky tang) OR (ky nang)) van hoc. hieu ve cam xuc ((va dang) or (hoa lang)) de cua tre".
• Adding a wildcard symbol may retrieve word variants: vu dai ((ky tang) OR (ky nang)) van hoc. hieu ve cam xuc ((va dang) or (hoa lang)) de cua tre*.
