Hi,  
I would like to copy indices/data between 2 clusters.  
For example, copy every 1/2/15 minutes the data from the index in cluster1 to cluster2.  
I would like the data to be live or near live in cluster2.  
So if a document is created now in cluster1, I would like to see it in cluster2 immediately, or within a couple of minutes.  
What is the best approach?  
Is using the the [search API](https://www.elastic.co/guide/en/elasticsearch/reference/current/search-search.html) best solution?  
e.g.

```auto
GET /<index>/_search

```

Also, how can I validate I am not querying duplicate documents?  
Maybe something like saving the last timestamp queried and use it in the next query?!

Thanks!

Thank you!  
I was not aware of this functionality.  
I will go over the documentation.
