> WordBreakSolrSpellChecker incorrectly adds parenthesis when breaking words

> Key: SOLR-12284
> URL: https://issues.apache.org/jira/browse/SOLR-12284
> Project: Solr
> Issue Type: Improvement
> Security Level: Public(Default Security Level. Issues are Public) 
> Components: spellchecker
> Affects Versions: 7.3
> Reporter: James Dyer

> 
> When using WordBreakSolrSpellChecker to break single words into multiple, the \
> collation queries include parenthesis around the original term.  In some cases, \
> this causes required terms to become optional and users get spurious nonsensical \
> collation results. For instance, if I search: +eward +smith 
> ...If +ward +smith is a match, it might give a collation like: (+e +ward) +smith
> ...This requires either the "e" or the "ward" to exist, but not both.  But users \
> are more likely to want both terms to be required, so it would be better if it was \
> not adding parenthesis. This might be the cause of SOLR-5995 and [this SO \
> issue|https://stackoverflow.com/questions/23849747/solr-wordbreak-spellchecker-breaking-words-into-letters-excessive-breaking]
