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

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