[elephant-devel] Re: NIL values in secondary indices

it is somehow special in map-index, and inherently in 
GET-INSTANCES-BY-RANGE --
if start is NIL it starts from beginning, it end is NIL it iterates to the 
end, so (NIL, NIL)
range should mean all the sequence. behaviour you're observing is wrong, i 
guess.

question is _why_ should you use GET-INSTANCES-BY-RANGE when
you can do this via GET-INSTANCES-BY-VALUE?
