• If you are trying to use Boolean operators, they must be ALL CAPS: ((((tan ying) OR (ran ying))) OR (fan ying)) sein die last teaching change roberto n ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((tan ying) OR (ran ying))) or (fan ying)) sein die last teaching change roberto n ;~".
• Adding a wildcard symbol may retrieve word variants: ((((tan ying) OR (ran ying))) or (fan ying)) sein die last teaching change roberto n ;*.
