Google (and other search providers) include the page title, URL and some description in search results. For search within a large organisation, where all results are from the same domain, is there any value in including the URL beyond supporting users who may want to print the results?
It depends. One consensus seems to be to remove such information from intranet search results in favor of including a more human-readable location (http://www.steptwo.com.au/papers/cmb_searchresults/index.html), however other groups recommend including it as a valuable piece of contextual information (i.e., "Oh, that URL is under http://projectA.mycompany.com/..., I definitely don't want that site"). I tend to fall in this second camp.
What you decide will depend on a number of factors:
Let's see why a public search engine includes a URI first.
From the domain perspective (e.g. example.com/)
In Intranet, categorization become the an important part to assist searching.
Think URI in term of home address, if the URI is well organized,
It would be a benefit for user to filter the noise rapidly.
