I am collecting suricata events with elasticsearch.  
I want to create an alert through correlation analysis for suricata event.

For example, when the following events are saved

```auto
{
    rule.event: "event a"
    src.ip: "10.0.0.1"
    dst.ip: "10.0.0.2"
},
{
    rule.event: "event b"
    src.ip: "10.0.0.2"
    dst.ip: "10.0.0.1"
}

```

I want to create an alert by combining events with the same src.ip and dst.ip.  
Are these queries possible with DQL?

I want to make correlation rules for logs of devices other than suricata.  
Are all of these operations possible with query in elasticsearch?
