feng douglas » zeng douglas, long douglas, farr douglas
first thing » first things, first hint, first third
daun yang » dan yang, du yang, tan yang
yan risk » can risk, main risk, plan risk
yan his » man his

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: daun yang ((yan his) OR (yan risk)) ((first thing) OR ((last OR east) thing)) feng douglas mair ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "daun yang ((yan his) OR (yan risk)) ((first thing) or ((last or east) thing)) feng douglas mair ;~".
• Adding a wildcard symbol may retrieve word variants: daun yang ((yan his) OR (yan risk)) ((first thing) or ((last or east) thing)) feng douglas mair ;*.
