Search with synonym support

Questions
1

Is there support for search with synonyms in L7 or is it Loop54 the only way to go?
E.g., Setup search so that “Iphone11”, “Iphone 11”, “Iphone 11X” is treated as the same word in the search.

Is there a way to use Lucenes supported features that are not published through Litiums API?

Litium version: 7

It does not exists any inbuilt functionality for synonyms.

It is possible to use some of the features that lucene.net have; i.e. analyzers with different type of tokenizers and filters. See to old thread about Lucene stemming.
