Hi,
I am using ES 2.3 version and using \_reindex api; however, I could not find corresponding api in java transport client. Also, I could not find any documentation regarding it. For time being, to use the api I am using rest api.
Can some one please point out the java transport client api for these two new features - \_reindex and \_update\_by\_query?
Regards,
Nikhil

Hi,
reindex and update\_by\_query are implemented inside reindex module (aka built-in plugin). In order to use their Java API, you need to:
1. Add org.elasticsearch.module:reindex to the dependency.
2. Add ReindexPlugin when you init Transport Client.
The discussions at [Reindex Java API](https://discuss.elastic.co/t/reindex-java-api/45923) might be helpful.

Trango
