如何将404个URL分解为单个单词并搜索它们？

I am working on my Page not found 404 template. For some reason my conditional doesn't seem to work right:

What I am trying to achieve is to break down the path and search for each expression. I remove - and _ from the expression.

$s = preg_replace("/(.*)-(html|htm|php|asp|aspx)$/","$1",$wp_query->query_vars['name']);
            $posts = query_posts('post_type=any&name='.$s);
            $s = str_replace("-"," ",$s);
            $s = str_replace("_"," ",$s);
            if (count($posts) == 0) {
                $posts = query_posts('post_type=any&s='.$s);
            }
            if (count($posts) > 0) {
                echo "<ol><li>";
                echo "<p>Were you looking for <strong>one of the following</strong> posts or pages?</p>";               
                echo "<ul>";
                foreach ($posts as $post) {
                    echo '<li><a href="'.get_permalink($post->ID).'">'.$post->post_title.'</a></li>';
                }
                echo "</ul>";
}

If I type "products_s"

It says:

in Let me help you find what you came here for: Were you looking for one of the following posts or pages? Products

So It finds products, which is great.

But if i type in "products_services"

Even though I am expecting to get products and services pages listed as above, it doesn't finds anything.

What am I missing?

Thanks,

I have never used wordpress but I do notice you change the queryposts()

In the first check you do:

$posts = query_posts('post_type=any&name='.$s); //notice &name=

In the second check you do:

$posts = query_posts('post_type=any&s='.$s); // notice &s=

It all depends what is happening inside of queryposts(). Personally I would just pass the string through with '_' '-' and explode('-',$string) on the other side to split them into an array.

The reason it's not working for you is because Wordpress's search only returns posts that meet all the words in the query. So, "products_s" turns into "products s" and both "products" and "s" are in the word Products. So Products gets returned. "products_ducts" would return the same page.

If you had a page named Products and Services, you'd get a result with your second search.

Perhaps you could split the string at the spaces and perform a search for each word and append the results to each other.
