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