• The words AND, OR and NOT may confuse the search; try adding quotes: "dong yang ya ida credit ((trading case) or (((training visit) OR (training crisis)))) long seo ;~".
• Adding a wildcard symbol may retrieve word variants: dong yang ya ida credit ((trading case) or (((training visit) OR (training crisis)))) long seo ;*.
