Hows does https://www.elastic.co/guide/en/elasticsearch/guide/current/ngrams-compound-words.html2 work with 5.x?
Looks like a bug, since it does not work with 5.x. minumum_should_match gets ignored.
the ngram filter does actually work, but if I setup a query I want a minimum match of found ngrams otherwise I would get lots of useless documents in the result.
