Odd results, searching for games

Hi there, I'm playing around with using the GiantBomb API to retrieve game covers and details based on an input. At the moment, because I'm just testing and haven't actually incorporated something if I search for:

"Activision Destiny Vanguard Armoury Edition Xbox One Unsealed"

I dont get any correct results for the actual game but plenty of wrong ones. If I however just search for Destiny I get more desirable results. Is there something I am doing wrong, usually adding more keywords in the search string should make things more accurate, not less accurate?

Thank You
Steven

@stevenbrewis can you show the exact URL you use? (minus your api key obviously). for most games the platform isn't part of the name of the game itself.
