Perhaps you should try some spelling variations:
"john stuart hill" » "john stuart hall", "john stuart hull", "john stuart mills"
"john stuart ll" » "john stuart l", "john stuart hall", "john stuart ll.d"
"john stuart mill" » "john stuart ill", "john stuart bill", "john stuart mall"

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: (((("john stuart mill") OR ("john stuart hill"))) OR ("john stuart ll")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"john stuart mill\") OR (\"john stuart hill\"))) or (\"john stuart ll\"))".
• Removing quotes may allow a broader search: (((( john stuart mill ) OR ( john stuart hill ))) or ( john stuart ll )).
• Adding a wildcard symbol may retrieve word variants: (((("john stuart mill") OR ("john stuart hill"))) or ("john stuart ll"))*.
