Hi, [this page](https://www.elastic.co/guide/en/elasticsearch/reference/current/analysis-synonym-graph-tokenfilter.html) on synonym graphs reads:

> The `synonym_graph` token filter allows to easily handle synonyms, including multi-word synonyms correctly during the analysis process.

Does that mean that a simple "synonyms" filter will necessarily introduce errors when working with multi-word synonyms? Should it be deprecated then? Or are there still cases where I would prefer the simple synonyms filter to synonym graph?

Thanks
