Parsing address returns blank result

I tried the below address and receive no response at all, not even an error.

WHITEROSE SHOPPING CENTER,LOWER LEVEL,LEEDS,LS11 8LL

I done this using curl from the command line as shown in the example

curl --data "WHITEROSE SHOPPING CENTER,LOWER LEVEL,LEEDS,LS11 8LL" http://sorting-office.openaddressesuk.org/address
