The keyword index is more suitable for online help and
online manuals.

The full text search is more suitable for online information
retrieval.

for more info and supporting arguments, read on (medium to
long response to Tim Altom, Tony Ioven, Richard Mateosian,
Bonni Graham, and scot -at- hci -dot- com -dot- au)

I include search in the training. I provide full text
search with all the Boolean operators (and variations thereof).
I include proximity searches and frequency count. Results
are on the fly, so you don't have to enter a new search
argument to refine the results. I provide for naming and
saving search results as well. I emphasize that the search
results are only as good as *you* the user are at preparing
the search criteria. This is a very important part of the
training. Sometimes we even have fun proving the software
functions as described.

All true, but I am working with a large information database
that is growing every day. I can't imagine putting it in the
field without the full text search.

How many keyword indexes have you used that were prepared
with *thoughtful consideration of the user's needs?* If
you, the writer, need to prepare a perfect keyword index,
then by all means, go for it. But, don't take away my
full text boolean search (assuming DASD is cheap). I need
it, I use it, I am comfortable with it, and I want it. I
am the user, and you irritate me when you take away my
good and useful tool.

I think Bill Horton said, "the more navigational tools,
the better." I agree with Bill--somewhat, provided the
tools don't make it too easy to enter hyperspace.

I disagree for all the reasons I gave. Perhaps the
difference is the size and structure of the database.

NOTE: I do use a keyword index. I use it for the help
files for the online software. The difference is the use,
and it's a BIG IMPORTANT DIFFERENCE. For online
information retrieval, not online help, and not an online
manual, you need the full text search with all the bells
and whistles.
