• The words AND, OR and NOT may confuse the search; try adding quotes: "cost planning laws a rein ((((yuan kang) OR (chan kang))) or (((yang jui) or (yang xi)))) hong g ;~".
• Adding a wildcard symbol may retrieve word variants: cost planning laws a rein ((((yuan kang) OR (chan kang))) or (((yang jui) or (yang xi)))) hong g ;*.
