----------------------------------

This is a problem with collations in general: By default, it simply mashes the
top corrections together, often resulting in nonsense. The solution is to set
"spellcheck.maxCollationTries" to a non-zero value. Doing so will cause the
spellchecker to vet the collation possibilities against the index, resulting in
collations that are guaranteed to generate hits.
{quote}
If wordbreak gives back a suggestion of a combined word, a suggestion with a
word fragment with more hits is still ranked higher in the collation.
So "spa llcheck" is preferred over "spellcheck" if spa has more hits then
spellcheck.

it would also be handy if "spell check" would result in the suggestion
"spellcheck". Or is this already possible?
This is the core of what this issue (really LUCENE-3523) is all about, provided
that "spellcheck" is in the dictionary&index you're using.

Never got this working as no suggestions were given when both word fragments
were spelled correctly and the combined word was in the index. (when making
typo in combined word the word was returned as suggestion)

> A SpellCheckComponent enhancement, leveraging the WordBreakSpellChecker from
> LUCENE-3523:
> - Detect spelling errors resulting from misplaced whitespace without the use
> of shingle-based dictionaries.
> - Seamlessly integrate word-break suggestions with single-word spelling
> corrections from the existing FileBased-, IndexBased- or Direct- spell
> checkers.
> - Provide collation support for word-break errors including cases where the
> user has a mix of single-word spelling errors and word-break errors in the
> same query.
> - Provide shard support.
