Perhaps you should try some spelling variations:
"its colonization history" » "its communication history", "its organization history", "its cooperation history", "anti colonization history", "jews colonization history", "mars colonization history"
"mass communication sector" » "mass telecommunication sector", "mass telecommunications sector", "mass communication series", "maps communication sector"
"anti colonial israel" » "_ anticolonial israel", "a colonial israel", "ii colonial israel"

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: "((((\"its colonization history\") OR (\"anti colonial israel\"))) OR (\"mass communication sector\"))~".
• Removing quotes may allow a broader search: (((( its colonization history ) OR ( anti colonial israel ))) OR ( mass communication sector ))~.
• Adding a wildcard symbol may retrieve word variants: (((("its colonization history") OR ("anti colonial israel"))) OR ("mass communication sector"))*.
