[Java] What happened to .cache(true) on filters in 2.0?

Elastic Stack Elasticsearch

I am doing the API upgrade on our system and am currently doing the jump from 1.X to 2.X. What happened to explicit caching on the filters? I did some Googling and didn't see anything about a replacement command or whether or not ES is going to handle this automatically now.

Example code from my 1.X API:

BoolFilterBuilder combinedFilter = FilterBuilders.boolFilter().cache(true);

As of 2.0, elasticsearch figures out whether to cache filters by itself, based on how often they are reused. See https://www.elastic.co/guide/en/elasticsearch/reference/current/breaking_20_query_dsl_changes.html#_filter_auto_caching and https://www.elastic.co/blog/better-query-execution-coming-elasticsearch-2-0.
