Hi gang, any reason why trying to use these primitive matches state Ill-formed sdfpath?

%closerthan:/cameras/camera1,10
%closerthan(/cameras/camera1, 10)
%fartherthan:/cameras/camera1,10
%fartherthan(/cameras/camera1, 10)

Funnily this works:
%bound:/cameras/camera1

But this doesn't:
%bound(/cameras/camera1)

Houdini 18.5.532

Thanks.

The closerthan and fartherthan auto-collections, and the support for arguments in parentheses are all features of 19.0, not 18.5. See https://www.sidefx.com/docs/houdini18.5/solaris/pattern.html [www.sidefx.com] for documentation of pattern matching in 18.5.
