Global

The Global tab provides the global administration option settings for:

• Global Administrator Account: The user account set here is the default account to notify via email when errors occur or other activity relating to the Watson™ Explorer Engine software occurs.
• Admin URL: The URL of the admin CGI script.
• Installation Label: A descriptor for this installation of Watson Explorer Engine. This text will be displayed on the left side of the Administration Tool. This option is useful when regularly working with multiple Watson Explorer Engine instances.
• Use minimal collection listing: When enabled, the search collection list interface displays the Any Search Collection (minimal) list instead of the default Any Search Collection.
• HTTP Referrer Whitelist: This field can be used to explicitly allow HTTP requests to be sent from hosts other than the Watson Explorer Engine host. This will allow IBM® Watson Explorer pages to be embedded in iframes (and other HTML elements) running on servers other than the server the Watson Explorer Engine is running on.

  It is best to explicitly name the servers, rather than using regular expressions. For example, if your server naming convention is "$purpose-$operating_system-$letter$number$number$number.domain.com", you would specify "web-linux-A456\.domain\.com".

  This option uses regular expressions to check whether the received HTTP_Referer field contains an allowed host. If you use a regular expression that is incorrect or too permissive, a host that you do not intend to have access might match the regular expression. If you wanted to allow ALL of your web servers to access your Watson Explorer Engine installation, you could use the following regular expression: "web-(linux|windows)-[a-z][0-9]{3}\.domain\.com". This means all servers with the name "web followed by a dash followed by either linux OR windows followed by a dash followed by ONE letter in the range A to Z followed by EXACTLY three numbers dot domain dot com". For more information on the proper syntax for expressions, see POSIX Regular Expression Syntax and Examples.
