This is my logstash config file:  
input {  
jdbc {  
jdbc\_driver\_library =\> "/home/vatsa/logstash/mysql-connector-java-5.1.38-bin.jar"  
jdbc\_driver\_class =\> "com.mysql.jdbc.Driver"  
jdbc\_connection\_string =\> "jdbc:mysql://localhost:3306/LC"  
jdbc\_user =\> "root"  
jdbc\_password =\> ""

```
statement => "select * from test where ID<=45000"

```

}  
}  
output {  
elasticsearch {

```
    index => "det"
    document_type => "contact"
    document_id => "%{ID}"
    hosts => "localhost:9200"
}

```

}  
and i run it using , logstash/bin/logstash -f /home/vatsa/logs/conts-jdbc.conf

Next time,if i change the query to ID\>45000 AND ID\<=90000 and i run it ,the data in previous index gets replaced by the data.  
How do i add this data to the data present in the previous index?
