Alan Woodward commented on LUCENE-8644:
---------------------------------------
This patch changes the signature of newSynonymQuery from `(Term[)]` to
`(Map<Term, String>)`, a map of terms to their types. It also makes some
changes to GraphTokenStreamFiniteStrings to keep track of the type attribute.
It doesn't make any changes to query parser behaviour - this is purely to make
the information available.
> Pass token types to QueryBuilder.newSynonymQuery()

> SynonymGraphFilter distinguishes between input tokens and tokens that it
> injects into the token stream by setting the TypeAttribute to SYNONYM.
> QueryBuilder currently ignores this information, but it would be useful to
> pass it through to the newSynonymQuery() method, as this would allow
> queryparsers to apply differential boosts to synonyms and original terms.
