Perhaps you should try some spelling variations:
"ra duncan smith" » "ra duncan sarah", "_ duncan smith", "mr duncan smith", "j duncan smith"
"jon duncan smith" » "jon duncan sarah", "john duncan smith", "j duncan smith", "colin duncan smith"
"ra duncan scott" » "ra duncan scotus", "ra duncan stone", "_ duncan scott", "mr duncan scott", "j duncan scott"
"ian duncan sir" » "brian duncan sir", "a duncan sir", "innes duncan sir", "ian duncan i", "ian duncan sarah"

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