Can I edit work item search result column display?

Hi Hakki,

Is it a predefined query that you are trying to add more columns to the results view. 
This would need editing the Configuration source and is not recommended. 

Instead, you could create a copy by using "Save Copy"
and
use the "Columns Display" page on the "Edit Query" view
to choose the fields you want to add on to the results display.

You can even re-oder (Move Up / Move Down) the chosen fields on the Columns Display page

Hope this helps.

Regards,
Dinesh
