Perhaps you should try some spelling variations:
"colonize" » "colonized", "colonies", "colonial"
"coloniald" » "colonial", "coloniali", "colonials"
"coloniale" » "coloniales", "colonial", "koloniale"
"colonicd" » "colonic", "colonico", "colonized"

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: ("colonize" OR (("coloniald" OR "coloniale") OR "colonicd")).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(\"colonize\" or ((\"coloniald\" OR \"coloniale\") or \"colonicd\"))".
• Removing quotes may allow a broader search: ( colonize or (( coloniald OR coloniale ) or colonicd )).
• Adding a wildcard symbol may retrieve word variants: ("colonize" or (("coloniald" OR "coloniale") or "colonicd"))*.
