Duplicate Content Script

I have an existing Duplicate content script that checks the TITLE of my articles and returns count greater than 1. so the script will catch TITLE like this Article 1 - How To Make Money Easily Article 2 - How To Make Money Easily BUT my existing script will **NOT** catch articles titles like this Article 1 - How To Make Money Easily! Article 2 - How To Make Money Easily. OR Article 1 - How To Make Money Easily! Article 2 - How To Make Money Easily. OR Article 1 - "How To Make Money Easily" Article 2 - How To Make Money Easily! I need someone to update my existing script to return titles as shown above as duplicate. But the scripts MUST recognise title like this Article 1 - How To Make Money Easily - PART 1 Article 2 - How To Make Money Easily - PART 2
