Perhaps you should try some spelling variations:
"wikt:interlude" » "witt:interlude", "wit:interlude", "wik:interlude"
"wilt:interlude" » "walt:interlude", "wild:interlude", "wilf:interlude"
"wait:interlude" » "waite:interlude", "walt:interlude", "want:interlude"
"litt:interludio" » "pitt:interludio", "lita:interludio", "liut:interludio", "litt:intermedio"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("wikt:interlude" OR "wilt:interlude") OR ("wait:interlude" OR "litt:interludio"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wikt:interlude\" OR \"wilt:interlude\") OR (\"wait:interlude\" OR \"litt:interludio\"))*".
• Removing quotes may allow a broader search: (( wikt:interlude OR wilt:interlude ) OR ( wait:interlude OR litt:interludio ))*.
