 The valuestream documents are not currently being used by OP_VALUE_RANGE
 (and also OP_VALUE_GE, etc) as far as I can tell.  My main evidence for
 this is some profiling traces of a pure VALUE_RANGE search which doesn't
 call any ValueStreamDocument methods, but I also can't see any code which
 would allow a ValueStreamDocument to be used.

 I'd expected ValueStreamDocument to be used for these, since it should
 reduce the amount of seeking around they need to do, and speed them up
 considerably.  I think the ValueStreamDocument would need to become a
 member of MultiMatch, be created in the constructor, and passed to
 LocalSubMatch, and on to the query optimiser, to allow it to be used.
