Configure VS 2010 Help for a specific subject

Using VS2008, you could set Document Explorer to开发者_如何学C limit your search to specific subjects using the Technology dropdown, which made for finding info on a specific subject very easy, as it was limited to a subset of available subject. How is the accomplished in the new VS2010 help?

The VS2010 help at the moment, is very hazy. When I search for Task, or task, or c# task. re the new Task library in .net, it returns a whole bundle of irrelevancy...

Any ideas.

Apparently the Document Explorer is not compatible with VS 2010. There is an extension called H3Viewer developed by a third party which apparently provides similar functionality.
