Perhaps you should try some spelling variations:
"ian duncan smith" » "ian duncan sarah", "brian duncan smith", "innes duncan smith"
"jon duncan smith" » "jon duncan sarah", "john duncan smith", "j duncan smith", "colin duncan smith"
"ian duncan scott" » "ian duncan scotus", "ian duncan stone", "brian duncan scott", "innes duncan scott"
"ian duncan sir" » "brian duncan sir", "innes duncan sir", "ian duncan sarah"
"a duncan i" » "ra duncan i", "_ duncan i", "j 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 scott"))) OR ((("ian duncan sir") OR ("a 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 scott\"))) or (((\"ian duncan sir\") or (\"a duncan i\"))))) or (\"jon duncan smith\"))".
• Removing quotes may allow a broader search: (((((( ian duncan smith ) OR ( ian duncan scott ))) or ((( ian duncan sir ) or ( a duncan i ))))) or ( jon duncan smith )).
• Adding a wildcard symbol may retrieve word variants: (((((("ian duncan smith") OR ("ian duncan scott"))) or ((("ian duncan sir") or ("a duncan i"))))) or ("jon duncan smith"))*.
