Perhaps you should try some spelling variations:
"litt:interludio" » "pitt:interludio", "liut:interludio", "lita:interludio", "litt:intermedio"
"waitt:interludio" » "waitt:intermedio", "witt:interludio", "watt:interludio", "waite:interludio", "waitet:interludio", "waltt:interludio", "wantt:interludio"
"wait:interludio" » "wait:intermedio", "waite:interludio", "walt:interludio", "want:interludio"
"wit:interlude" » "whit:interlude", "witt:interlude"

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

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