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