Windows Search Desktop bug(s)!

The help text in the Search Desktop function of XP should be edited by
Microsoft to clearly point out that if you embed an "=" sign in a keyword,
Desktop Search is unable to find the keyword.

ie, if in a Word.doc you embed a keyword like "car=Ford" in the File
Properties of the .doc, Windows search can't find it when you either search
for "car=Ford" or even if you type the special search syntax,
"keywords:car=Ford".

Not sure if there may be other 'illegal' characters that also cause this
problem; that's Microsoft's job to figure out. In any event, it ought to be
mentioned in the help system for Windows Search.

One clue to this is buried in the help system under the topic "Problems
finding a file" is the shocking statement that "Windows Search indexes the
first 2 MB of text (excluding symbols) in each document."

Maybe Windows is interpreting an equals sign as a symbol...if so, what else
does it arbitrarily consider to be a symbol?

Also, I think users should all be warned in a very noticable way rather than
via this 'buried' statement, of the 2,000 MB limitation on indexing for each
file! People have no reason not to assume that the Windows indexing service
is faithfully indexing all the content of their files, but this limitation
can omit vast amounts of text from their index, making considerable amounts
of information, 'un-findable'. I think this is a rather glaring deficiency
that users should be warned about, much more clearly, up front, before they
start relying on Windows Search.
