Perhaps you should try some spelling variations:
"york relationships" » "rock relationships", "look relationships", "park relationships"
"work relationships" » "network relationships", "working relationships", "work relationss"
"work relationship" » "network relationship", "working relationship", "work relations"

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