Okay, let's do this one more time:
Say you searched for 250 x 190 x 80
And say these are your choices:
250 1 1
250 500 1
250 1 500
250 190 1
250 190 500
240 180 70
*CLEARLY* the first 3 choices are useless. Yet each has a perfect match on length.
Equally clearly the next 2 choices are useless, even though each has a perfect match on both length an height.
So the only reasonable choice is the last one, even though none of its dimensions is a perfect match.
You see my point? THERE IS NO POINT in looking for a perfect match as a separate operation. What you really want is, as I suggested, the CLOSEST match on all 3 dimensions. But, again, you have to tell us what CLOSEST then means.
Is it the sum of the differences being closest to zero? The product of the differences being closest to zero? What?
