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

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