Refresh=wait_for for Elasticsearch 2.2

Hi there,
I am using Elasticsearch version 2.2 and I am asking if there is any possibility for an update query to wait until changes have been made visible for search. In other words I am looking for a solution similar to "refresh=wait_for" but for version 2.2.
Is there possibly a way to ask Elasticsearch whether an index is "dirty", i.e. whether latest results are not yet available for search?
Thanks,
Michail

No. You need to upgrade to 5.x at least.
