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