Perhaps you should try some spelling variations:
"_ decolonization models" » "_ decolonization notes", "_ decolonization across", "_ decolonization case", "decolonization _ models"
"re colonization history" » "re communication history", "re organization history", "re cooperation history", "pro colonization history", "_ colonization history", "jews colonization history"
"war decolonisation from" » "war decolonization from", "war decolonisation _", "war decolonisation 1", "_ decolonisation from", "4.4 decolonisation from"

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: (((("war decolonisation from") OR ("_ decolonization models"))) OR ("re colonization history"))~.
• Removing quotes may allow a broader search: (((( war decolonisation from ) or ( _ decolonization models ))) or ( re colonization history ))~.
• Adding a wildcard symbol may retrieve word variants: (((("war decolonisation from") or ("_ decolonization models"))) or ("re colonization history"))*.
