---------------------------------
Summary: WordBreakSolrSpellChecker incorrectly adds parenthesis
when breaking words
Key: SOLR-12284
URL: https://issues.apache.org/jira/browse/SOLR-12284
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Components: spellchecker
Affects Versions: 7.3
Reporter: James Dyer
Assignee: 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]
