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

You may be able to get more results by adjusting your search query.

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