Perhaps you should try some spelling variations:
"_ colonization history" » "_ communication history", "_ organization history", "_ cooperation history", "_ decolonization history", "decolonization _ history"
"mobile communication theory" » "mobile communication technology"
"re colonization israel" » "re communication israel", "re colonization still", "re decolonization islam", "pro colonization israel", "jews colonization israel", "mars colonization israel"

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: (((("re colonization israel") OR ("_ colonization history"))) OR ("mobile communication theory"))~.
• Removing quotes may allow a broader search: (((( re colonization israel ) or ( _ colonization history ))) or ( mobile communication theory ))~.
• Adding a wildcard symbol may retrieve word variants: (((("re colonization israel") or ("_ colonization history"))) or ("mobile communication theory"))*.
