Hello, I am trying to get latest timestamp from an index by using elasticsearch input plugin with query as

input {  
elasticsearch {  
hosts =\> "${ES\_HOST}:9200"  
index=\>"myindex"  
query =\> '{ "query": { "match\_all": { } }, "sort": [{"@timestamp":{"order":"desc"}}],"size":1 }'  
size=\>1  
}  
}

However, I get all documents in the index.

Is this a known issue, since the same query returns only one result in kibana?
