Perhaps you should try some spelling variations:
"ra duncan scott" » "ra duncan scotus", "ra duncan stone", "_ duncan scott", "mr duncan scott", "m duncan scott"
"jon duncan smith" » "jon duncan sarah", "john duncan smith", "ian duncan smith", "colin duncan smith"
"j duncan smith" » "j duncan sarah", "_ duncan smith", "mr duncan smith"
"jon duncan sir" » "john duncan sir", "ian duncan sir", "colin duncan sir", "jon duncan i", "jon 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: (("ra duncan scott") OR ((((("jon duncan smith") OR ("j duncan smith"))) OR ("jon duncan sir")))).
• Removing quotes may allow a broader search: (( ra duncan scott ) or ((((( jon duncan smith ) or ( j duncan smith ))) or ( jon duncan sir )))).
• Adding a wildcard symbol may retrieve word variants: (("ra duncan scott") or ((((("jon duncan smith") or ("j duncan smith"))) or ("jon duncan sir"))))*.
