The new format produces output as (querying for pithon+progremming,

In this example the best suggestions are the first ones. Some queries may
return a suggestion which is very close to the query word, but with relatively
low frequency (Lucene sorts results by distance first). In that case
suggestions that are somewhat farther but with a much higher frequency should
be chosen.
> Spell-check should return frequencies of word and suggestions

> URL: https://issues.apache.org/jira/browse/SOLR-395
> Project: Solr
> Issue Type: Improvement
> Components: spellchecker
> Affects Versions: 1.3
> Reporter: Mike Krimerman
> Assignee: Mike Klaas
> Priority: Minor
> Fix For: 1.3
>
> Attachments: extended_results.diff, returnFrequencies.patch
>
>
> When issuing a spell-check, the word being searched for might be present in
> the index with a very low frequency (i.e. a misspelling that made it's way
> into the index). It might therefore be helpful if the client receives the
> frequency of the word plus the frequencies of each of the suggestions.
> This feature should be optional (using a URL param).
