What is the hunspell version used by elasticsearch?

[stulentsev (Sergio Tulentsev)]

I'm trying to use a Dutch hunspell dictionary from LibreOffice: nl_NL.aff\nl_NL - libreoffice/dictionaries - main, development dictionaries repository

But it has this warning:

BEWARE: THIS AFFIX FILE AND DICTIONARY REQUIRE HUNSPELL 1.2.8 AS MINIMAL VERSION

I can't create an index with this, so I assume elasticsearch 6.2.3 has a lower version of hunspell

Elasticsearch::Transport::Transport::Errors::InternalServerError: [500] {"error":{"root_cause":[{"type":"remote_transport_exception","reason":"[es-glossary-test-sergio-node-vm3][10.0.0.13:9300][indices:admin/create]"}],"type":"illegal_state_exception","reason":"failed to load hunspell dictionary for locale: nl_NL","caused_by":{"type":"illegal_argument_exception","reason":"expected only one flag, got: Kc"}},"status":500}

Does this error indeed mean that ES's hunspell is not modern enough? If yes, can I update it? If not, why wouldn't it work?

This workaround fixes it for me: Dutch hunspell doesn't work in 1.7.1?

"Fixes" in the sense "ES can now create the index". Didn't yet check if it's actually doing what it should.

Still, it'd be nice if it "just worked".
