Hi Team,

My objective is to add latest ES index documents to kafka  
Below is my logstash conf -\>  
'''  
input {  
elasticsearch {  
hosts =\> ["IP"]  
index =\> "Index\_name"  
query =\> '{"query":{"range":{"@timestamp":{"gte": "now-5m"}}}}'  
}  
}

output {  
kafka {  
codec =\> json  
topic\_id =\> "topic\_name"  
bootstrap\_servers =\> "IP"  
}  
}  
'''  
it works. But everytime I run it added all the documents to kafka.  
It should add only latest updates from index but not all.

Do i need to add date filter, or change the query part? Kindly assist how to do this?
