I feel so noobish for posting this. I've been unable to force getRange to work! It displays more posts than I want.

public function getCombinedNews($limit) {
      $name = $this->Title;
      $entries = DataObject::get("BlogEntry", "Tags LIKE '%{$name}%'");
      $articles = $this->Articles();
      $articles->sort('Created', 'DESC');
      if(isset($limit)) {
      return $articles;

It returns the range as a new DataObjectSet so it needs to be

$articles = $articles->getRange(0,$limit);

Thanks for the tip! Unfortunately, that didn't work. To make sure it wasn't the if(isset()) part, I commented it out so that the limit would get applied regardless. It returns no objects at all now!

Then I would be checking exactly what you're feeding the function. getRange is just

   public function getRange($offset, $length) {
      $set = array_slice($this->items, (int)$offset, (int)$length);
      return new DataObjectSet($set);

As you can see it's just array_slice() with one variable for where to start and one for how many to grab. Likely your $limit variable is either 0 or something else that gets turned into 0 by the int cast. Also since your function definition requires that $limit is sent to the function your isset will always return true.
