When using the XML API to your Google Mini or Search Appliance, if a page in the search results does not have a <title> in it’s HTML, then it does not have a ‘T’ node (in GSP/RES/R/T) in the XML returned for the search.

The XSLT controlling the look of the web frontend on the box automatically replaces the title with the URL of the page instead (with the http:// taken off the start.) With the XML API you can decide to replace it with anything you like, but this behaviour is certainly preferred by the clients I’ve had to set it up for. Best of all would be for all pages to have a title, but there could well be some that slip through testing (when there is testing) so it’s best to be prepared for it.
