Perhaps you should try some spelling variations:
"colin duncan sir" » "john duncan sir", "colin duncan i", "colin duncan sarah"
"ian duncan smith" » "ian duncan sarah", "ian duncan scott", "brian duncan smith", "a duncan smith", "jon duncan smith"
"j duncan sir" » "j duncan i", "j duncan sarah", "_ duncan sir", "mr 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 ((("j duncan sir") OR ("colin duncan sir"))))*.
• Removing quotes may allow a broader search: (( ian duncan smith ) or ((( j duncan sir ) or ( colin duncan sir ))))*.
