Why is it when I request some postcodes from Bing maps I get an incorrect coordinates http://dev.virtualearth.net/REST/v1/Locations?postalCode=IM1+1LD&countryRegion=GB&o=xml&key=MY_BING_KEY
While when I request it using this I get the correct ones http://dev.virtualearth.net/REST/v1/Locations?postalCode=IM1&1LD&countryRegion=GB&o=xml&key=MY_BING_KEY
i.e. when I send IM1+1LD as a postalcode incorrect results are returned, while sending IM1&1LD returns the correct results in the response.
