• If you are trying to use Boolean operators, they must be ALL CAPS: long learning tony j ((((das yang) OR (dan yang))) OR (das lange)) jie song hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "long learning tony j ((((das yang) OR (dan yang))) or (das lange)) jie song hai ;~".
• Adding a wildcard symbol may retrieve word variants: long learning tony j ((((das yang) OR (dan yang))) or (das lange)) jie song hai ;*.
