I am working on One Website - Multiple Store functionality. My products are displayed according to store views. I am opening both store urls on two different tabs. But when i search products displayed from stores and when i checkout then also in checkout both products are displayed which are add in cart.I want search and checkout works store specific products only.
Instead of opening in different tabs try to open both in different browser and see if you still have same issue.
system -> configuration -> Customer Configuration and first tab account sharing option
