Is there some way to reindex all documents of an index?

Elastic Stack Elasticsearch

I was having issues about handling multi word synonyms and the solution i've found was contracting the synonym to a "canonical form" at index time like explained here.

But when i add a new synonym to the list, all documents should be reindexed, right ?. What's the recommended way of doing that ?

You can use the reindex API to do this. Index into a second index and then use an alias to point to that one.
