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

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 ("a duncan smith"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"ian duncan smith\") OR (\"ian duncan scott\"))) or (\"a duncan smith\"))*".
• Removing quotes may allow a broader search: (((( ian duncan smith ) OR ( ian duncan scott ))) or ( a duncan smith ))*.
