Perhaps you should try some spelling variations:
"j duncan scotus" » "j duns scotus", "_ duncan scotus", "mr duncan scotus"
"ian duncan sarah" » "ian duncan adam", "ian duncan gray", "ian duncan shaw", "brian duncan sarah", "a duncan sarah", "jon duncan sarah"
"j duncan smith" » "j duncan sir", "j duncan scott", "_ duncan smith", "mr 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 sarah") OR ((("j duncan smith") OR ("j duncan scotus")))).
• Removing quotes may allow a broader search: (( ian duncan sarah ) or ((( j duncan smith ) or ( j duncan scotus )))).
• Adding a wildcard symbol may retrieve word variants: (("ian duncan sarah") or ((("j duncan smith") or ("j duncan scotus"))))*.
