Perhaps you should try some spelling variations:
nursing practices » nursing practice, nursing practical, farming practices
practices service » practice service, practices overview, practices section
active services » active service, native services, adaptive services
active devices » passive devices, assistive devices

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