Perhaps you should try some spelling variations:
"witt:interlude" » "pitt:interlude", "litt:interlude", "witt:interludio"
"wickt:interlude" » "wickt:interludio", "wicht:interlude", "wicki:interlude", "wicks:interlude", "nickt:interlude", "dickt:interlude", "rickt:interlude"
"windt:interlude" » "windt:interludio", "wind:interlude"
"wick:interlude" » "wick:interludio", "nick:interlude", "dick:interlude", "rick:interlude"

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

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