How can I display the request referrer?

By default, the product page breadcrumb is built based on the referrer.

For example, if a customer performs a search for "shirt" and then clicks on a listing result, the breadcrumb on the product page will be Home > Search for “shirt” > Casual Shirt.

To disable this functionality, use dontUseReferer():

\Aero\Store\Facades\Breadcrumb::dontUseReferer();
