How to clear the search result list on selection of another shop in b2b?

Hi All,

In the generic search of b2b app, in the left side frame we will have a tab called transaction and when i give * and click on search, i will get the list of the orders present based on the criteria below that page and when i open the order, it will appear in the history page of the right side frame. But in our app, we have provided a custom link to go to the select-shop page where the user can select another shop. After selection of another shop, i should not get the searched orders and the orders in the history page. How should i nullify the search and the history pages??

Thanks in Advance.

Regards,

Lakshman.
