Comment 4 for bug 237103

The lookup window is probably the most complex screen in Silva. This adds yet more complexity but it's a great feature.

It should be possible to check whether the linked object exists, then get it's container, and use that path as the url. Or maybe check whether the linked object is a container, and if not, go to its container. This could handle the not found use case, and bring the user to the container where the link destination used to be.

Of course, the enclosing container could be not found too, so I guess we should check whether it exists, and if not, just bring up the lookup window in the current container.
