 Currently, OP_SYNONYM simply adds up the wdfs of the member terms to
 calculate the wdf of the resulting item.  However, it might be useful to
 allow OP_SYNONYM to be told to modify the wdfs of the member terms (using
 an integer muliplier).  This would correspond functionally to the "weight"
 function implemented in scriptindex, which allows the weight of a field to
 be modified at index time by multiplying the wdf, but would allow the
 weights to be adjusted at search-time without requiring a re-index.

 I'm not sure where in the API this would fit, but it's something to
 consider before merging the OP_SYNONYM branch to trunk.
