The real question to answer is what types of queries you're planning on
making. Rather than look at it from indexing forward, consider it from
searching backwards.
How will users query using those keyword phrases?

I'm getting a bit more serious about the final form of our lucene
index. Each document has DocNumber, Authors, Title, Abstract, and
Keywords. By Keywords, I mean a comma separated list, each entry
having possibly many terms in a phrase like:
temporal infomax, finite state automata, Markov chains,
conditional entropy, neural information processing
I presume I should be using a field "Keywords" which have many
"entries" or "instances" per document (one per comma separated
phrase). But I'm not sure the right way to handle all this. My
assumption is that I should analyze them individually, just as we do
for free text (the Abstract, for example), thus in the example above
having 5 entries of the nature
doc.add(Field.Text("Keywords", "finite state automata"));
etc, analyzing them because these are author-supplied strings with no
canonical form.
For guidance, I looked in the archive and found the attached email,
but I didn't see the answer. (I'm not concerned about the dups, I
presume that is equivalent to a boos of some sort) Does this seem
right?
Thanks once again.

Hi!
What happens if I do this:
doc.add(Field.Text("foo", "bar"));
doc.add(Field.Text("foo", "blah"));
Is there a field "foo" with value "blah" or are there two "foo"s
(actually not
possible) or is there one "foo" with the values "bar" and "blah"?
And what does happen in this case:
doc.add(Field.Text("foo", "bar"));
doc.add(Field.Text("foo", "bar"));
doc.add(Field.Text("foo", "bar"));
Does lucene store this only once?
