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