Perhaps you should try some spelling variations:
"put–call party" » "put–all party", "put–fall party", "put–called party"
"put–call parity" » "put–call party", "put–call parts", "put–call part"
"put–all parity" » "put–all party", "put–all parts", "put–all part"

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: (((((("put–call parity") OR ("put–call party"))) OR ("put–cell polarity"))) OR ("put–all parity"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((\"put–call parity\") OR (\"put–call party\"))) or (\"put–cell polarity\"))) or (\"put–all parity\"))*".
• Removing quotes may allow a broader search: (((((( put–call parity ) OR ( put–call party ))) or ( put–cell polarity ))) or ( put–all parity ))*.
