How to get a record by \_id (or other fields) from ElasticSearch in a logstash filter stage?

I know the Elasticsearch provides the Get API like: curl -XHEAD -i '[http://localhost:9200/twitter/tweet/1](http://localhost:9200/twitter/tweet/1)' to get a record from ElasticSearch(ES) , but I don't know how to get the same record from logstash filter.

Can anyone help? Thanks in advance.
