Rather than making the boost a property of the document, I would
recommend that the boost be a field.  That way, you could have different
boost values for different types of searches.  Consider a database
of books.  One "boost" field could be the sales rank, and another the
price; one search would rank cheaper books higher, and another could
rank more popular books higher, based on the choice of boost field.
