Perhaps you should try some spelling variations:
"re decolonisation from" » "re decolonization from", "re decolonisation _", "re decolonisation 1", "_ decolonisation from", "4.4 decolonisation from", "_ decolonization from"
"re cooperation history" » "re corporation history", "re federation history", "de cooperation history", "area cooperation history", "rate cooperation history"
"_ colonization still" » "_ colonization failed", "_ colonization israel", "_ colonization songs", "_ decolonization still", "decolonization _ still"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"re decolonisation from\") OR (\"_ colonization still\"))) OR (\"re cooperation history\"))~".
• Removing quotes may allow a broader search: (((( re decolonisation from ) OR ( _ colonization still ))) OR ( re cooperation history ))~.
• Adding a wildcard symbol may retrieve word variants: (((("re decolonisation from") OR ("_ colonization still"))) OR ("re cooperation history"))*.
