Hey there!
There are some things to mention if it comes to using filters (e.g. Filter - Search) on the search results page/template. It starts with query parameters in the url. Using Filter - Search should update the search term in the url and not remove or hiding it. Right now, bricks is removing all query variables which means, if you change the search term and refresh the page you get back to the homepage because everything which is important for displaying the search results template is removed. Maybe you could give us an implemented functionality to change the search url from ?s= to /search/{search_term} and update the term on Filter - Search input change.
