>> It's amazing what you can find if you care to use the help browser!

(Such blatant and unwarranted sarcasm!)  IF you already know where to look, 
you mean.  Browsing for "vector calculus" yields nothing.  There are many 
articles related to vectors, yet searching for "vector" also yields nothing 
(except VectorQ).  "vector" isn't a keyword for the VectorAnalysis package? 
 Amazing!

Browsing for "calculus" works, but that isn't an obvious choice, if I'm 
interested in vector calculus.

Most of the time, the help browser is useless unless you already know the 
exact name of what you're trying to find.  Sometimes it's useless even 
then, as for example if you're interested in TextForm.

Wolfram: Give us a search tool, not a keyword lookup tool.

Or, if it has to be keyword lookup, PUT IN THE KEYWORDS.
