Hi,

I am using logstash to put my data from couchdb into elasticsearch. I just noticed that my \_rev field in not ported to elasticsearch. Do I need to do something special in my logstash config file to have that in elasticsearch. Prompt help will be appreciated. I only have input and output sections in my logstash config file.  
Here is my input in logstash config file:

```
couchdb_changes {
    db => "users"
    sequence_path => "seq_files\users_couchdb_seq"
    tags => ["users"]
}

```

and here is my output:

```
if "users" in [tags] {
   elasticsearch { 
   document_id => "%{[@metadata][_id]}"
   index => "users_index"
   hosts => ["127.0.0.1:9200"]
}

```

Thanks,  
imad.
