Perhaps you should try some spelling variations:
"ra duncan smith" » "ra duncan sarah", "ra duncan scott", "_ duncan smith", "mr duncan smith", "j duncan smith"
"bruce duncan smith" » "bruce duncan sarah", "bruce duncan scott"
"bruce duncan sir" » "bruce duncan i", "bruce duncan sarah"

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 ((("bruce duncan smith") OR ("bruce duncan sir")))).
• Removing quotes may allow a broader search: (( ra duncan smith ) or ((( bruce duncan smith ) or ( bruce duncan sir )))).
• Adding a wildcard symbol may retrieve word variants: (("ra duncan smith") or ((("bruce duncan smith") or ("bruce duncan sir"))))*.
