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

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