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