Perhaps you should try some spelling variations:
learning practical » learning practices, containing practical, learning statistical
practice services » practices services, practice service, practices service
nursing practical » using practical, building practical, solving practical

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: "((\"sociology AND nursing practice services\") or (\"sociology AND ((nursing practical) OR (learning practical)) service\"))".
• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"sociology and nursing practice services\\") or (\\"sociology and ((nursing practical) OR (learning practical)) service\\"))\"".
• Removing quotes may allow a broader search: (( sociology and nursing practice services ) or ( sociology and ((nursing practical) OR (learning practical)) service )).
