Perhaps you should try some spelling variations:
"brian duncan smith" » "ian duncan smith", "brian duncan sarah", "brian duncan scott"
"brian duncan sir" » "ian duncan sir", "brian duncan i", "brian duncan sarah"
"bruce duncan smith" » "bruce duncan sarah", "bruce duncan scott"

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 ("brian duncan sir"))) OR ("bruce duncan smith")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"brian duncan smith\") OR (\"brian duncan sir\"))) or (\"bruce duncan smith\"))".
• Removing quotes may allow a broader search: (((( brian duncan smith ) OR ( brian duncan sir ))) or ( bruce duncan smith )).
• Adding a wildcard symbol may retrieve word variants: (((("brian duncan smith") OR ("brian duncan sir"))) or ("bruce duncan smith"))*.
