"collective direct reports" » "collection direct reports", "collective dream reports", "collective effect reports", "collective indirect reports"
"protective effects reports" » "protective effects report", "protective effects repousse", "protective defect reports"
"protective effect reports" » "protective defect reports", "protective effects report", "protective affect reported"

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: (("collective direct reports") OR ((("protective effects reports") OR ("protective effect reports")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"collective direct reports\") or (((\"protective effects reports\") OR (\"protective effect reports\"))))".
• Removing quotes may allow a broader search: (( collective direct reports ) or ((( protective effects reports ) OR ( protective effect reports )))).
• Adding a wildcard symbol may retrieve word variants: (("collective direct reports") or ((("protective effects reports") OR ("protective effect reports"))))*.
