Perhaps you should try some spelling variations:
"ian duncan smith" » "ian duncan sarah", "ian duncan scott", "brian duncan smith", "a duncan smith", "jon duncan smith"
"brra duncan smith" » "brra duncan sarah", "brra duncan scott", "brian duncan smith", "ra duncan smith", "bard duncan smith"
"brra duncan sir" » "brian duncan sir", "ra duncan sir", "bard duncan sir", "brra duncan i", "brra 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 ((("brra duncan smith") OR ("brra duncan sir"))))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"ian duncan smith\") or (((\"brra duncan smith\") OR (\"brra duncan sir\"))))*".
• Removing quotes may allow a broader search: (( ian duncan smith ) or ((( brra duncan smith ) OR ( brra duncan sir ))))*.
