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