Perhaps you should try some spelling variations:
douglas mair » douglas mary, douglas a, douglas m
feng douglas » zeng douglas, long douglas, farr douglas
first thing » first things, first third, first teaching
first hint » first joint, first hand, first high
daun yang » dan yang, du yang, tan yang
yang yan » yang yang, wang yan, yang fan
yan his » man his, yan risk
last » east, past, list

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 ((((first hint) OR (first thing))) OR (last thing)) feng douglas mair ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "daun yang yan his ((((first hint) OR (first thing))) or (last thing)) feng douglas mair ;~".
• Adding a wildcard symbol may retrieve word variants: daun yang yan his ((((first hint) OR (first thing))) or (last thing)) feng douglas mair ;*.
