Flickr Fumble

While I like the flickr interface on the whole, its response to multiple tags entered into the search-field is non-standard, un-useful and annoying.

For example, in the first screenshot, I search for "van roadtrip" looking for images that are tagged with both "van" and "roadtrip". But, in the second shot, you can see the flickr concatenates these terms and fails to find any photos with the tag "vanroadtrip"

Personally, I don't see how this is ever useful (it can be avoided by going to the "advanced search" screen and choosing "all of these tags" but I think that should be the default behavior (like web search engines)
