Hi,

Just want to know can we perform math operation with lucene query in kibana. I have a variable and it's value is in GB. I want to convert it in KB in lucene query something like this.

$mem = 4

Kibana lucene query like:

usemem:\>($mem \* 1024 \* 1024)

Thanks  
Niraj

No you cannot.

You can with a scripted field though.
