Perhaps you should try some spelling variations:
"its communication history" » "its telecommunication history", "its communication sector", "its communication theory", "nets communication history", "c's communication history", "mass communication history"
"its colonization history" » "its organization history", "its cooperation history", "its civilization history", "anti colonization history", "jews colonization history", "mars colonization history"
"_ federation history" » "_ migration history", "_ federalism history", "_ federated history"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (((("its colonization history") OR ("its communication history"))) or ("_ federation history"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (((("its colonization history") OR ("its communication history"))) OR ("_ federation history")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"its colonization history\") OR (\"its communication history\"))) or (\"_ federation history\"))".
• Removing quotes may allow a broader search: (((( its colonization history ) OR ( its communication history ))) or ( _ federation history )).
• Adding a wildcard symbol may retrieve word variants: (((("its colonization history") OR ("its communication history"))) or ("_ federation history"))*.
