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