Magento - 2 stores with differents shopping carts and differents search

How can I configure Magento to have 2 stores with differents shopping carts and开发者_如何学运维 different search, but the same customers ?

Thanks for help.

Its rather easy

1. setup two different websites and store-views to separate the carts and searches
2. set up customer accounts to be global from system > configuration > customer > customer configuration

and the later is just $$$$ profit
