我对ElasticPress.

在成功安装和连接WordPress和ElasticPress并为数百篇文章编制索引以进行测试之后，我发现一切正常，直到我尝试创建自定义WP_Query. 结果页只有标题行，但未显示帖子内容。在search.php 这是我写的

$wp_query = new WP_Query( array(
                    \'ep_integrate\'   => true,
                    \'post_type\'      => \'post\',
                    \'posts_per_page\' => 20,
                    \'tax_query\' => array(
                        array(
                            \'taxonomy\' => \'category\',
                            \'terms\'    => array( get_query_var(\'cat\') ),
                            \'field\'    => \'term_id\',
                        ),
                    ),
                ) );


                if ( $wp_query->have_posts() ) {

                    // Start the loop.
                    while ( $wp_query->have_posts() ) : $wp_query->the_post();

                        /**
                         * Run the loop for the search to output the results.
                         * If you want to overload this in a child theme then include a file
                         * called content-search.php and that will be used instead.
                         */
                        get_template_part(\'template-parts/content\', \'search\');

                        // End the loop.
                    endwhile;

                    // Previous/next page navigation.
                    the_posts_pagination(array(
                        \'prev_text\' => __(\'Previous page\', \'twentysixteen\'),
                        \'next_text\' => __(\'Next page\', \'twentysixteen\'),
                        \'before_page_number\' => \'<span class="meta-nav screen-reader-text">\' . __(\'Page\', \'twentysixteen\') . \' </span>\',
                    ));

                    wp_reset_postdata();

                    // If no content, include the "No posts found" template.
                } else {

                    get_template_part(\'template-parts/content\', \'none\');
                }

不幸的是，我没有找到任何关于如何在构建自定义查询时正确使用ElasticPress的信息。所有教程都很简单，展示了如何编写新的WP_Query 结果是在没有任何其他编程的情况下生成的。

全局post变量不是空的，页面上仍然缺少post内容。WordPress为4.6.1，ElasticPress为2.1.2。

有人能告诉我创建自定义查询和显示结果的正确方法吗。我知道ES，但我几乎是WP的初学者。

function elasticpress_search( $wp_query ) { 
    if ( is_search()  ) { 
        $query->set( \'ep_integrate\', true ); }     
}

add_action( \'pre_get_posts\', \'elasticpress_search\' );
