What works very good for me: 1.) Keep the tokenized field (KeywordTokenizerFilter, WordDelimiterFilter) (like you described you had) 2.) create an additional field that stores uses the String type with the same content (use copy field to fill either) 3.) use facet.prefix instead of terms.prefix for searching the suggestions 4.) to your query add also the String field as a facet, and return the results from that field as suggestion list. They will include the complete String "canon pixma mp500" for example. The other field can only return facets based on tokens. You probably never want that as facets.
So your query was alright and the "canon" (2) facet count probably is the two occurrences that you listed, but as the field was tokenized, only tokens would be returned as facets. You need to have an additional field of pure String type to get the complete value as a facet back. In general, it worked out fine for me to create String fields as return values for facets while using the tokenized fields for searching and the actual facet queries.
