I replace bp header search form with google search form (name = ‘q’ ) , then added this code:
function bp_google_action_search_site(){
global $bp;
if ( bp_is_current_component( bp_get_search_slug() ) )
bp_core_load_template( apply_filters( 'bp_core_template_search_template', 'search-google' ) );
}
remove_action( 'bp_init', 'bp_core_action_search_site', 5 );
add_action( 'bp_init', 'bp_google_action_search_site', 10 );

The search action get redirected to homepage.
How to redirect the search result page?

Try using esc_url

On my mobile so can’t test it.
