Perhaps you should try some spelling variations:
"_ dunciad sarah" » "_ duncan sarah", "_ dunciad early", "_ duncan sara"
"ian duncan smith" » "ian duncan sarah", "ian duncan sir", "ian duncan scott", "brian duncan smith", "jon duncan smith", "innes duncan smith"
"a duncan smith" » "a duncan sarah", "a duncan sir", "a duncan scott", "ra duncan smith", "_ duncan smith", "j duncan smith"

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 ((("a duncan smith") OR ("_ dunciad sarah")))).
• Removing quotes may allow a broader search: (( ian duncan smith ) or ((( a duncan smith ) or ( _ dunciad sarah )))).
• Adding a wildcard symbol may retrieve word variants: (("ian duncan smith") or ((("a duncan smith") or ("_ dunciad sarah"))))*.
