Hi,  
I have couch db with ~500k docs and couchdb river with configuration from  
example [http://www.elasticsearch.org/guide/reference/river/couchdb.html](http://www.elasticsearch.org/guide/reference/river/couchdb.html).  
After update document in couch the changes in ES come effect after some  
period (5 - 15 seconds).  
Using \*flush[http://www.elasticsearch.org/guide/reference/api/admin-indices-flush.html](http://www.elasticsearch.org/guide/reference/api/admin-indices-flush.html)  
, \*after each update document in couch, helps to take changes in ES  
immediatelly.  
But it seems it's not good practice.  
Maybe has another way to resolve my problem?

Thanks.

Flush has nothing to do with indexed document from couchdb. When searching  
for documents indexed from couchdb, there two important time based aspects:

1. How long does it take to get it from the \_changes stream and index it.
2. The refresh interval which controls when an indexed document will become  
visible, defaults to 1 second.
