Perhaps you should try some spelling variations:
"wit:interlude" » "whit:interlude", "witt:interlude", "wait:interlude", "wit:interludio"
"litt:interlude" » "litt:interludio", "pitt:interlude", "lita:interlude", "liut:interlude"
"kant:interlude" » "kant:interludio"
"walte:interlude" » "walte:interludio", "walter:interlude", "waste:interlude", "walt:interlude"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("wit:interlude" OR "litt:interlude") OR ("kant:interlude" OR "walte:interlude"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"wit:interlude\" OR \"litt:interlude\") OR (\"kant:interlude\" OR \"walte:interlude\"))".
• Removing quotes may allow a broader search: (( wit:interlude OR litt:interlude ) OR ( kant:interlude OR walte:interlude )).
• Adding a wildcard symbol may retrieve word variants: (("wit:interlude" OR "litt:interlude") OR ("kant:interlude" OR "walte:interlude"))*.
