Exclude pages from wp query with ElasticPress

code.md

1. Prevent pages being indexed

add_filter('ep_pre_index_post', function ($should_index, $post_args, $post) {
    // Exclude pages by post type
    if ($post->post_type === 'page') {
        return false;
    }

    return $should_index;
}, 10, 3);

2. Filter query result

add_filter('ep_wp_query_search_query_args', function ($query_args) {
    if (!is_admin() && isset($query_args['post_type']) && is_array($query_args['post_type'])) {
        // Remove 'page' from the post types searched
        $query_args['post_type'] = array_diff($query_args['post_type'], ['page']);
    }

    return $query_args;
});

3. Reindex Elasticsearch

wp elasticpress index --setup
