`more_like_this` filter doesn't understand index alias in doc reference

After an upgrade to 2.0.0 I noticed that my working more_like_this query broke and stopped finding matches.

I have figured out that the problem is in my usage of alias name in the docs section of the query. When changing the alias name to a real index name the query worked as expected. See more details about this issue on github https://github.com/elastic/elasticsearch/issues/14944.

Am I missing something?

Does this help? - https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking_20_query_dsl_changes.html#_more_like_this_2

Nope, it doesn't. I do use the query correctly.
But thanks for trying
