Perhaps you should try some spelling variations:
"witt:interlude" » "pitt:interlude", "litt:interlude", "witt:interludio", "whitt:interlude", "waitt:interlude"
"whitt:interlude" » "whitt:interludio", "whitty:interlude", "white:interlude", "whit:interlude"
"wit:intermedio" » "whit:intermedio", "wait:intermedio"
"whitt:intermedio" » "whitty:intermedio", "white:intermedio", "whit:intermedio"

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 ("wit:intermedio" OR "whitt:intermedio")) OR "whitt:interlude")~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"witt:interlude\" OR (\"wit:intermedio\" OR \"whitt:intermedio\")) OR \"whitt:interlude\")".
• Removing quotes may allow a broader search: (( witt:interlude OR ( wit:intermedio OR whitt:intermedio )) OR whitt:interlude ).
• Adding a wildcard symbol may retrieve word variants: (("witt:interlude" OR ("wit:intermedio" OR "whitt:intermedio")) OR "whitt:interlude")*.
