Okke Klein commented on SOLR-2993:
----------------------------------
If I am not mistaken the functionality from
https://issues.apache.org/jira/browse/SOLR-2585 can also be achieved in
DirectSolrSpellChecker with thresholdTokenFrequency parameter. So I patched
trunk with this patch and the corresponding Lucene patch and did some
experimenting.
The misplaced whitespaces were fixed and proper suggestions were returned.
However if both word parts resulted in suggestions, the collation made no sense.
Hypothetical example:
"spe llcheck" would give suggestions "spa" and "spellcheck" and collate this
into "spa spellcheck"
In my use case I never got any results back when one of the parts had a typo.
So "spe llchek" would not give any suggestions.
For my use case it would also be handy if "spell check" would result in the
suggestion "spellcheck".
Or is this already possible?

> 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.
