Seeking Search Guidance

[Byron Turner]

I've read all the search, find, offset and related articles, but I'm 
missing something.  I have no problem finding individual items, but I 
want to do something more like (actually exactly like) what the rev 
documentation does (on a smaller scale) I want it to list all off first 
items of my field (which it does) the when someone begins to type in 
the field limit the results down to those that match.  I can get it to 
find one thing that matches and If I create a very slow script I can 
get what I want but it can't come close to keeping up with a hunt and 
peck typist.  So what's the secret?
