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

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