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

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