Comment (by Olly Betts):

 > A somewhat common case where we get a potentially large boolean OR is
 for a wildcard weighted by OP_SYNONYM (the default).

 Except that in this case we do need all the subpostlists to be moved to
 the matching document so that the `SynonymPostList` can call `get_wdf()`.
