Perhaps you should try some spelling variations:
"_ duncan scott" » "_ duncan scotus", "_ duncan stone"
"ian duncan shaw" » "ian duncan sarah", "brian duncan shaw", "a duncan shaw", "jon duncan shaw"
"ian duncan adam" » "brian duncan adam", "a duncan adam", "jon duncan adam"

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: (("_ duncan scott") OR ((("ian duncan adam") OR ("ian duncan shaw")))).
• Removing quotes may allow a broader search: (( _ duncan scott ) or ((( ian duncan adam ) or ( ian duncan shaw )))).
• Adding a wildcard symbol may retrieve word variants: (("_ duncan scott") or ((("ian duncan adam") or ("ian duncan shaw"))))*.
