Unfortunately this API is not supported by the Java client. I probably need to use the ClusterStateRequest as explained in this [discussion](https://discuss.elastic.co/t/how-to-do--cat-indices-index-name-with-reg-ex-in-java/79936).

Somehow I feel this is getting over complicated.  
**Doing a realtime lookup for a unique id across multiple indices (time series) sounds like a common use case.**

Am I miss using Elasticsearch or is my set-up wrong? Is there a better way than getting all indices names and running a Multi Get to achieve this?
