Can the boosting be greater than 2.0? For example,
"field.setBoost((float)20.0)".

Daniel,
As I hope you've seen from the other messages on this thread, this is
by design.
What you've shown is _not_ boost working improperly. Boosts are part
of the score via the fieldNorm value, and I'm certain that your
boosts are being taking into account for scoring. Boosts are not
retrievable as-is from the Document object after a search. We should
javadoc that getter more clearly and note that it is really only
valid when you create a Document, not when you retrieve an existing one.
