"Unknown query type:org.apache.lucene.search.SynonymQuery" when nested

[ https://issues.apache.org/jira/browse/LUCENE-8495?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bjarke Mortensen updated LUCENE-8495:
-------------------------------------
Affects Version/s: master (8.0)
> ComplexPhraseQuery.rewrite throws "Unknown query type:org.apache.lucene.search.SynonymQuery" when nested BooleanQuery contains a SynonymQuery
> ----------------------------------------------------------------------------------------------------------------------------------------------
>
> Key: LUCENE-8495
> URL: https://issues.apache.org/jira/browse/LUCENE-8495
> Project: Lucene - Core
> Issue Type: Bug
> Components: core/queryparser
> Affects Versions: 7.4, master (8.0)
> Reporter: Bjarke Mortensen
> Priority: Major
> Attachments: 0001-Added-support-for-nested-synonym-queries-in-ComplexP.patch
>
>
> When using nested queries in ComplexPhrases, and a part of the query is a SynonymQuery, an exception is thrown from addComplexPhraseClause:
> {{throw new IllegalArgumentException("Unknown query type:"}}
> {{ + childQuery.getClass().getName());}}
> Examples (dogs and tv are synonyms):
> {{"(cats OR dogs) cigar"}}
> "platform* (video* OR tv)"~10
> The bug is similar in nature to LUCENE-8305, in that SynonymQuery support was added to ComplexPhraseQueryParser (in LUCENE-7695), but was not expanded to nested queries.
> The fix is similar to the one in LUCENE-8305, namely to add the same logic in addComplexPhraseClause as in rewrite.
> See attached patch.
