Perhaps you should try some spelling variations:
"une communication sector" » "une telecommunication sector", "une telecommunications sector", "une communication series", "d'une communication sector", "ante communication sector", "de communication sector"
"its colonization history" » "its communication history", "its organization history", "its cooperation history", "anti colonization history", "jews colonization history", "mars colonization history"
"_ colonization failed" » "_ colonization still", "_ organizations failed"

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