I want to create a WP_Query which functions as the WordPress search. I
thought this was just a matter of passing in the following as the
args, but that doesn't seem to be working. Can anyone confirm that
this is the right approach (and that I need to fix my own bug) or
suggest another approach, please? I do want to do this with WP_Query
if at all possible, rather than some wrapper function.

Thanks in advance.

Not to say it's the best method, depending on what you're doing, but  
it's reasonably straightforward and easy to maintain.

Currently I'm creating listings of recent posts in categories for use

$args = array(

        'post_status' => 'publish',
        'posts_per_page' => $num_posts,
        'orderby' => 'modified',
        'order' => 'DESC',
        'cat' => $cat_ids,
);
$new_wp_query = new WP_Query( $args );

I was hoping for something similar, using WP_Query, which would allow
me to return posts as per a WP search but with the results restricted
to a particular set of categories. I'm fine with using the WHERE
filters on the SQL generated by the WP_Query and so I could do my SQL
LIKE stuff here, but I hoped it might be possible to reuse the
existing code in WP_Query which manages the WP search results to
generate my restricted search results. (Seems like less code
duplication.)

I thought it might be as simple as:

$args = array(
        's' => $search_string,
);
$search_wp_query = new WP_Query( $args );

...but that doesn't seem to be working for me. :(

Are you suggesting that I should kick off a WP_Query as per my first
example and then use the WHERE filters to mess with the resultant SQL?

Thanks again.

P.S. Search Everything is certainly a nicely coded plugin. :)

// query for a given term ("search_term") in some given categories (7  
and 8)
$search_query = new WP_Query();
$search_posts = $search_query->query('s=search_term&cat=7,8');

// build loop
foreach($search_posts as $search_post) {
        setup_postdata($search_post);

        // do stuff

Though I'm not sure exactly what you are looking for, I *think* that what you want is to use "category__in"

$args = array(
        'post_type' => $post_type,
        'what_to_show' => 'posts',
        'post_status' => 'publish',
        'posts_per_page' => $num_posts,
        'orderby' => 'modified',
        'order' => 'DESC',
        'category__in' => explode(",",$cat_ids),  // Assumes $cat_ids is a comma separated string of category ids.
);
$new_wp_query = new WP_Query( $args );

If this isn't what you need, reply with more details and we'll see what we can do to help.
