The distinction between 'domain' and 'search' should be immaterial; the only difference is that a 'domain' option allows only a single domain name, and 'search' allows multiple domains. So the use of 'search' for a single domain is not a bug, and is more consistent with the case in which multiple domain names are specified.
Thanks for the report.
