Can you exclude certain categories from the search, eg Uncategorized

Hello,

You can use PRO plugin version for this. Its has feature to exclude any products by id, taxonomy or attribute right inside settings page.

Also you can try to use following code snippet:

add_filter( 'aws_exclude_products', 'aws_exclude_products' );
function aws_exclude_products( $filtered ) {

    $args = array(
        'posts_per_page'      => -1,
        'fields'              => 'ids',
        'post_type'           => 'product',
        'post_status'         => 'publish',
        'ignore_sticky_posts' => true,
        'suppress_filters'    => true,
        'no_found_rows'       => 1,
        'orderby'             => 'ID',
        'order'               => 'DESC',
        'lang'                => '',
        'tax_query'           => array(
            array(
                'taxonomy'            => 'product_cat',
                'field'               => 'id',
                'terms'               => array( %CATEGORIES_IDS% ),
                'operator'            => 'IN',
                'include_children' => true
            )
        )
    );

    $posts = get_posts( $args );

    foreach( $posts as $post_id ) {
        $filtered[] = $post_id;
    }

    return $filtered;
    
}

change %CATEGORIES_IDS% with IDs of categories that you want exclude from the search.
