Perhaps you should try some spelling variations:
"brian duncan smith" » "bruce duncan smith", "brian duncan sarah", "brian duncan sir", "bra duncan smith", "brjon duncan smith", "brinnes duncan smith"
"brian duncan scott" » "bruce duncan scott", "brian duncan scotus", "brian duncan stone", "bra duncan scott", "brjon duncan scott", "brinnes duncan scott"
"ian duncan smith" » "ian duncan sarah", "ian duncan sir", "a duncan smith", "jon duncan smith", "innes 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: (((("brian duncan smith") OR ("brian duncan scott"))) OR ("ian duncan smith")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"brian duncan smith\") OR (\"brian duncan scott\"))) or (\"ian duncan smith\"))".
• Removing quotes may allow a broader search: (((( brian duncan smith ) OR ( brian duncan scott ))) or ( ian duncan smith )).
• Adding a wildcard symbol may retrieve word variants: (((("brian duncan smith") OR ("brian duncan scott"))) or ("ian duncan smith"))*.
