Hi Matthew and Ian,
Thanks, I'll try that, but, in the meantime, I've been doing some reading
(Lucene in Action), and on pg. 159, section 5.3, it discusses "Querying on
multiple fields".
I was just about to try to what's described in that section, i.e., using
MultiFieldQueryParser.parse(), or, as another note on pg. 161 mentions, doing
something like:
doc.add(Field.Unstored("contents", contents + " " + summary);
So, I guess I'm a little confused (happens a lot :)!): In the situation I'm
talking about (starting with the Lucene demo and demo webapp, and trying to be
able to index and search more than just the "contents" field), do I not need to
use the MultiFieldQueryParser.parse() or do what they call "create a synthentic
content"?
Thanks,
Jim
