• The words AND, OR and NOT may confuse the search; try adding quotes: "((((dan yang) OR (tan yang))) or (fan ying)) (dido or dino) time last teaching chang roberto e ;~".
• Adding a wildcard symbol may retrieve word variants: ((((dan yang) OR (tan yang))) or (fan ying)) (dido or dino) time last teaching chang roberto e ;*.
