Comment(by richard):

 I can't see how you could apply SCALE_WEIGHT to the subqueries, since
 their weights aren't used: in OP_SYNOYNM, the weights are generated from
 the combined term frequency estimate and the sum of the wdfs - not by
 combining the weights of subqueries.

 You're quite right that we'll need to be careful not to violate the
 inequalities, though - I hadn't thought of that.
