Perhaps you should try some spelling variations:
":wikt:misplace" » ":wikt:misplaced", ":wikt:displaces", ":wikt:displac"
":wikt:displace" » ":wikt:display", ":wikt:displays"
":sink:displaced" » ":sink:displayd", ":sink:displaysd"
":sink:displaysd" » ":sink:displays", ":sink:displayd", ":sink:display"

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: ((":wikt:misplace" OR ":wikt:displace") OR (":wikt:displayed" OR (":sink:displaced" OR ":sink:displaysd"))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\":wikt:misplace\" or \":wikt:displace\") or (\":wikt:displayed\" or (\":sink:displaced\" OR \":sink:displaysd\")))".
• Removing quotes may allow a broader search: (( :wikt:misplace or :wikt:displace ) or ( :wikt:displayed or ( :sink:displaced OR :sink:displaysd ))).
• Adding a wildcard symbol may retrieve word variants: ((":wikt:misplace" or ":wikt:displace") or (":wikt:displayed" or (":sink:displaced" OR ":sink:displaysd")))*.
