Perhaps you should try some spelling variations:
"ian duncan smith" » "ian duncan sarah", "ian duncan scott", "brian duncan smith"
"jon duncan smith" » "jon duncan sarah", "jon duncan scott", "john duncan smith", "j duncan smith", "colin duncan smith"
"innes duncan sir" » "james duncan sir", "innes duncan sarah"
"ian duncan sir" » "brian duncan sir", "ian duncan sarah"
"a duncan i" » "ra duncan i", "_ duncan i", "j duncan i", "a duncan _", "a duncan m", "a duncan c"

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