died first » field first, mind first, dead first
kong john » king john, wong john, longo john

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: tan ((kong jin) OR (kong john)) died first things zhang ((douglas w) OR (douglas john)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tan ((kong jin) OR (kong john)) died first things zhang ((douglas w) or (douglas john)) ;~".
• Adding a wildcard symbol may retrieve word variants: tan ((kong jin) OR (kong john)) died first things zhang ((douglas w) or (douglas john)) ;*.
