Post processing query resut

Elastic Stack Elasticsearch

Hi All,
Is there any way to post process the result of a query result. For example, If I have a field called "distance" in the document which is stored in "meters", the result should give the distance in "Kilometer". Basically I should divide the value by 1000 and display it as part of result.

Thanks,

Have a look at script fields.

Hi Magnus,
Thank you for your reply. I tried this. But this create the modified field under fields object. Is there any way to modify the content inside source itself?
