请教Google Search Appliance 这个模组?

大家好，请问哪位用过 Google Search Appliance 这个模组？

我已经安装好了这个模组，在Google Appliance Settings设置时，有几个选项不知道从何而来，请教大家了。

1。Host Name:？
（Your Google Search Appliance host name or IP address (with http:// or https://), which were assigned when the appliance was set up.
You do not need to include "/search" at the end, or a trailing slash, but you should include a port number if needed.
Example: http://mygooglebox.com）

2。 Default client (front end):？
（The name of a valid front-end, defined when you set up the appliance.）
