>                 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.
