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

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 "colonized") OR ("coloniald" OR "colonicd"))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"colonize\" OR \"colonized\") or (\"coloniald\" or \"colonicd\"))*".
• Removing quotes may allow a broader search: (( colonize OR colonized ) or ( coloniald or colonicd ))*.
