A WebmasterWorld thread has discussion about a search on Bing for [digital camera]. If you search on Bing for that query, you will not only see search results that match [digital camera] but Bing will show you other related queries and their search results.
Bing will show you 3 additional results for each of the following related queries, they include: Digital Camera Brands, Digital Camera Types, Top 10 Digital Cameras, Digital Camera Repair and Digital Camera Accessories. Here is a video showing this:
The interesting part here is that this is somewhat like the Google knows best but not fully. Here Bing is showing you what you queried for first and then shows you other search results that they think would be useful.
