Answer 1

You can add this function in Your function.php

add_action( 'pre_get_posts', 'search_woocommerce_only' );

function search_woocommerce_only( $query ) {
  if( ! is_admin() && is_search() && $query->is_main_query() ) {
    $query->set( 'post_type', 'product' );
  }
}

Answer 2

//Alter the WordPress search to return ONLY products, no pages
function my_search_filter($query) {
    if ( $query->is_search && ! is_admin() ) {
        $query->set( 'post_type', 'product' );
        $query->is_post_type_archive = true;
    }
}
add_filter('pre_get_posts','my_search_filter', 9);
