Can i search data on hadoop using elasticsearch?

I am a noob in the es-Hadoop category. I have tried to read all the documents but am still confused regarding how es-hadoop works and do I need it.
The question is simple.
Can I search for data on Hadoop using elasticsearch?
Can I create weekly indexes in elasticsearch which saves in Hadoop? Will I be able to search through these indexes using elasticsearch?

In order to search data it has to be indexed into Elasticsearch. You can not search data stored in Hadoop. The connector provides utilities for moving between Elasticsearch and Hadoop but not querying across. Storing live indices in Hadoop is not supported, but you can store snapshots on HDFS.

Thanks a lot for the reply.
