如何使此代码仅搜索帖子而不搜索页面？ （wp_query）

Question

This is the code:

<?php global $wp_query;
$search_term=$_REQUEST['search-terms'];
if(empty($search_term))
$search_term=$_REQUEST['s'];
$wp_query->query("s=".$search_term);?>
<?php if ( have_posts() ) : ?>
<?php while(have_posts()):the_post(); global $post;?>

For some reason it shows both posts and pages in the results page. How can i exclude pages and show only posts?

I tried this but it's not working:

<?php global $wp_query;
$args = array_merge( $wp_query->query, array( 'post_type' => 'post' ) );
query_posts( $args );
$search_term=$_REQUEST['search-terms'];
if(empty($search_term))
$search_term=$_REQUEST['s'];
$wp_query->query("s=".$search_term);?>
<?php if ( have_posts() ) : ?>
<?php while(have_posts()):the_post(); global $post;?>

Please help is kinda urgent. I would really appreciate it.

Add a post type to your query.

<?php global $wp_query;
$search_term=$_REQUEST['search-terms'];
if(empty($search_term))
$search_term=$_REQUEST['s'];
$wp_query->query("post_type=post&s=".$search_term); ?>

<?php if ( have_posts() ) : ?>
<?php while(have_posts()):the_post(); global $post;?>

I changed your first code
