Stopping an Everything search

Currently, if I run an Everything search that will take a while to process, e.g:

FIND CLEAR QUERYENGINE=everythingglobal SHOWRESULTS=source,tab QUERY exact:ext:png height:1000..2000

(I don't have the height property indexed)

Is there any way to stop the search other than closing the tab?
Is there a command to halt an ongoing search and still have access to the results obtained up to that point?

Thanks.

Have you tried exiting Everything (e.g. via its tray icon)?

Yes...but it is not a very ideal solution so to speak. Since the search starts from Opus, I would like to be able to stop it from there.
