Syntax to update my scheduled search using REST?

[the_wolverine]

I'm trying to update the max_concurrent instances on my scheduled search from the default of 1 to 2. But the REST command doesn't appear to be working.

curl -k -u admin:changeme https://splunk:8089/servicesNS/admin/search/saved/searches/test_search -d 'max_concurrent=2' -d sharing=app

(Note: the url is correct)

Can someone spot the issue in my curl command?

Try without the single quotes for max_concurrent as well.

curl -k -u admin:changeme https://splunk:8089/servicesNS/admin/search/saved/searches/test_search -d max_concurrent=2 -d sharing=app

Is the argument not applicable when modifying a system configuration?
