Perhaps you should try some spelling variations:
"network relationship" » "network relationships", "network relations", "networks relational", "networking relationship", "netrisk relationship"
"work relationship" » "working relationship", "work relations", "risk relationship"
"work relationships" » "working relationships", "work relationss", "risk relationships"

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