Hash Object Return codes

[NeilConstable]

Just wondering is anyone knows of a list of Hash Object Return codes when using eth find method. I know a return code 0 means the value was found, and -2147450842 seems to mean it was not found. Are there any other return codes that we should be aware of. For example might a find fail for any other reason than the key not being present.

I have searched but can not find a list of return codes.
