I have a site which performs different search services. For example, some of my different searches are weather, events, and business search.
What's the best way to give the user a way to switch between these searches? Some companies that already do this are Google and the black bar on the top that directs to other Google search forms or services, Diapers.com which has different sites displayed in a way similar to Google, with navigation on the top. A different look for this is Google experiment with hidden navigation or the countless others that have probably tried differently.
