I've got a nifty little utility that adds this functionality on to a WinHelp 3.0
file. You've still got keywords (and oughta use them -- see below), but you've
got this tool, as well.

I'm usually writing to the LCD, too, but more often their LCD-ness has to do with
their comfort level with and skill at using computer, and not with their
knowledge of the field. So in terms of searching, I may NOT have included all
the terms they'll need in the keyword list.

Actually, this would only result in a "hit" if the text actually uses this string
anywhere in it, which it probably doesn't. The utlity I use ranks the topics in
terms of number of "hits" (number of times the term appears in the topic) on the
theory that if a term is mentioned frequently, that's the mostly likely target
topic. The utility also provides a kind of text-only preview area, so the user
can see if their chosen target is in fact the one they want before jumping there
and leaving the search tool.

But it doesn't have to be either/or. The utility I mentioned earlier allows
both, and I beleive the WinHelp 4.0 engine still allows keywords. And while it
give the writer the way out, a canny writer will not USE this way out. Full-text
searches are great if someone needs to look up a term you didn't think to include
as a keyword, *provided that term actually exists somewhere in the text*. In
other words, if the user searches "framis" and the thing is called a "widget",
they ain't never gonna find it. Keywords are STILL the only way to get
synonym-lookup in a help file.

Well, happy to oblige! ; )

I prefer to include both searching techniques -- I feel that the more entry
points you provide for users the more likely those users are to find the
information they require.

And speaking of taking the burden on ourselves, anyone else want to kick
Microsoft over that (*&( search mechansim that runs when you open a help file for
the first time? Couldn't they have put this in the compiler? GRRRRR.
