Hi, I'm wondering if it's possible to do an if do or sed in the queries.

For example,

```
message: foo

s/foo/bar/g

```

or something like

```
if {
    message: foo
    {
        flag:bar
    }
}
```

Hi,

Where do you want to do this in queries? in Kibana or elasticsearch?

Thanks,

Hi,

In Kibana or Grafana. Thanks!

Hi,

We don't know in grafana :). But it's definitely possible in Kibana. Kibana runs on elasticsearch. You have multiple ways of querying data in Kibana - using lucene or Kuery in 6.0 - which is Kibana's own query language.

Here are some tutorial examples for it: [https://www.youtube.com/watch?v=mMhnGjp8oOI](https://www.youtube.com/watch?v=mMhnGjp8oOI)  
Here is our Kibana documentation: [https://www.elastic.co/guide/en/kibana/current/search.html](https://www.elastic.co/guide/en/kibana/current/search.html)

Hope this helps.

Thanks,  
Bhavya

Hi,

All I see in those two links are about searching though. Nothing about searching and creating additional field with another value if a certain criteria is fulfilled.

Thanks for the help @bhavyarm!

I've decided to use LogStash instead to do what I wanted.

For those curious, I used the below;

```
if "foo" in [message] {
     mutate { add_field => { "flag" => "bar" } }
}

```

Thank you!
