There is no upper limit. These are floats. But they can be small too. Boost < 1 are 'under normal'.
One radix sorting trick is to boost one field 1000 and another field 5. If the first field is a string facet, this gives each group of results in one long query. Lucene sorting does radix also, of course, but sometimes it is not the best tool.
