 * Ello.
 * Google seems to have very little (or my search keywords are terrible) about the
   return codes on queries such as updating, deleting.
 * Would 0 or 1 be a successful return?

 * Assuming you mean using **WP_Query** class to query posts for example, the best
   way of getting this information is either reading [WP_Query Codex](http://codex.wordpress.org/Class_Reference/WP_Query)
   and/or looking into the source code of WordPress (file `wp-includes/query.php`
   or [query.php on WordPress SVN repo](https://core.trac.wordpress.org/browser/tags/4.1/src/wp-includes/query.php#L0)).
 * For example, function `query_posts()` returns array of posts when successful 
   or an empty array if there are no queried posts (as far as I can see from the
   source code).
