Hi all,

How can I know when es does the flush? Can I configure it?  
Is there JAVA API for the flush?

Thank you,  
Olga

- [Elasticsearch Platform — Find real-time answers at scale | Elastic](http://www.elasticsearch.org/guide/reference/api/admin-indices-flush.html)(there  
is a Java API for it).

Why do you need to explicitly call it?
