Perhaps you should try some spelling variations:
"a duncan scott" » "a duncan scotus", "a duncan stone", "_ duncan scott", "m duncan scott", "r duncan scott"
"jon duncan smith" » "jon duncan sarah", "jon duncan sir", "john duncan smith", "ian duncan smith", "colin duncan smith"
"ra duncan smith" » "ra duncan sarah", "ra duncan sir", "_ duncan smith", "mr duncan smith", "m duncan smith", "r_ duncan smith", "rm duncan smith", "rr duncan smith"
"j duncan smith" » "j duncan sarah", "j duncan sir", "_ duncan smith", "mr duncan smith"

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: (("jon duncan smith") OR ((((("ra duncan smith") OR ("j duncan smith"))) OR ("a duncan scott")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"jon duncan smith\") or (((((\"ra duncan smith\") OR (\"j duncan smith\"))) or (\"a duncan scott\"))))".
• Removing quotes may allow a broader search: (( jon duncan smith ) or ((((( ra duncan smith ) OR ( j duncan smith ))) or ( a duncan scott )))).
• Adding a wildcard symbol may retrieve word variants: (("jon duncan smith") or ((((("ra duncan smith") OR ("j duncan smith"))) or ("a duncan scott"))))*.
