Thread: Where does vantage stores the search query?

Where does vantage stores the search query?

Hi,
I am trying to extend the search form in the header, with a categories dropdown. I was able to get the categories in a dropdown and also search through the categories, but once a option is selected i am not sure how to keep the option selected on the search results page. However, the checkbox on the right does check the checkbox (of the category I am searching through).

Can anyone explain me further on how does info is stored in the vantage search function?

Thanks.
