Perhaps you should try some spelling variations:
"spanish social worker' party" » "polish social worker' party", "spanish colonial worker' party", "spanish social workers' party", "spanish social work' party", "spanish social world' party"
"swedish social worker' party" » "sweden social worker' party", "swedish social workers' party", "swedish social work' party", "swedish social world' party"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"spanish social worker' party\") OR (\"swedish social worker' party\"))".
• Removing quotes may allow a broader search: (( spanish social worker' party ) OR ( swedish social worker' party )).
• Adding a wildcard symbol may retrieve word variants: (("spanish social worker' party") OR ("swedish social worker' party"))*.
