Perhaps you should try some spelling variations:
"a modern proposal" » "a modest proposal", "a modeling proposal", "a modest proposals"
"a models proposal" » "a modest proposal", "a model proposals", "a models proposed", "dea models proposal", "a mode proposal"
"a model proposal" » "a modest proposal"

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: (((("a modern proposal") OR ("a models proposal"))) OR ("a model proposal")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"a modern proposal\") OR (\"a models proposal\"))) or (\"a model proposal\"))".
• Removing quotes may allow a broader search: (((( a modern proposal ) OR ( a models proposal ))) or ( a model proposal )).
• Adding a wildcard symbol may retrieve word variants: (((("a modern proposal") OR ("a models proposal"))) or ("a model proposal"))*.
