VS2008 Help: How can I limit the index & search to just topics I want?

Time was that I could F1 a symbol in my .cpp or .h file, and I'd be given a reasonable list of possible topics to delve into.

That was long, long ago.

These days, I press F1 and I'm rarely given information that is even vaguely, tangentially or tenuously related to the API or subsystem in question. Instead, I am deluged with Windows Mobile APIs, .NET gibberish, VB crud, ASP rigmarole, unrelated COM interfaces, etc.

I work with three libraries predominately:

• Win32 API
• C++ standard library (and the still supported C libraries)
• MFC

Does anyone know how to get the sadly unfocused hel开发者_开发问答p system in VS2008 to retrieve only those topics of actual relevance to the type of programming one is doing, as opposed to a search against every possible symbol of a similar name in every technology Microsoft has ever done?

Alternately - can you suggest better places to lookup details for MFC, Win32 API, and C++ programming in general? I'm a seasoned programmer, but I cannot remember every nuance and detail of every API, and I have this bizarre desire to let the computer do that remembering for me... if only I can figure out how to make it be genuinely helpful...
