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

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