Wordpress - multiple WP Query objects into one?

Question

In Wordpress it\'s possible to create own WP Querys for the loop. An example is this:

$my_query = new WP_Query(array(\'post_parent\' => 3, \'post_type\' =

In case you don't want to do it with SQL, this is how I did my search page.

Basic problem: When doing a meta_query, wordpress thinks I want the condition to be joined with "AND" instead of "OR".

So Wordpress looks for a page with title/content = "myContent" AND the aioseop_keyword "myContent". This (in my case) lead to zero results, despite there was a page with matching SEO keyword.

To get around this, I make two queries. Sounds simple, BUT: the Loop didn't want to recognize the posts, despite there are posts in the $post object. I found this solution after taking a look on the have_posts() function : it refers to other variables than just the $post object.

$term = get_search_query(); // same as $_GET['s']

# the normal search:
$wordpress_keyword_search =& new WP_Query(array(
  's'         => $term,
  'showposts' => -1
));

# now push already found post IDs to an array, so we can exclude them from the meta search.
foreach ($wordpress_keyword_search->posts as $post_)
  $exclusion[] = $post_->ID;


# now do the meta query search
$aioseop_keyword_search =& new WP_Query(array(
  'post__not_in' => $exclusion,
  'post_type' => 'any',
  'showposts' => -1,
  'meta_query' => array(            
    array(
      'key'       => '_aioseop_keywords',
      'value'     => $term,
      'compare'   => 'LIKE',
    )
  )
));

# merge the two array posts.
# post_count and found_posts must be added together also. 
# otherwise have_posts() returns false.
# see: http://core.trac.wordpress.org/browser/tags/3.6.1/wp-includes/query.php#L2886

$wordpress_keyword_search->posts       = array_merge($wordpress_keyword_search->posts, $aioseop_keyword_search->posts );
$wordpress_keyword_search->found_posts = $wordpress_keyword_search->found_posts + $aioseop_keyword_search->found_posts;
$wordpress_keyword_search->post_count  = $wordpress_keyword_search->post_count + $aioseop_keyword_search->post_count;

Then use this in a simple loop:

if ($wordpress_keyword_search->have_posts()) {
  while($wordpress_keyword_search->have_posts()) {
    $wordpress_keyword_search->the_post();
    # now you simply can:
    the_title();
    the_content();

  }
} else {
  echo '
Sorry, no posts found
';
}
