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

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