I have products with code 273547, 80273547 and 973547 in the shop.

When searching with 73547 all tree products are shown.
When searching with 273547 only one product is shown. I was expecting ro see product 80273547 as well.

Is there any setting to accomplish this?
In earlier versions of Hikashop (6.1.0) sthis worked as expected.
