• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing yan) OR (wing tan)) ((kant oder) or (kann die)) cost ratings risk bearing what ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing yan) OR (wing tan)) ((kant oder) or (kann die)) cost ratings risk bearing what ;*.
