title: Creating a plagiarism detector using google search appliance api
body: <p>i wish to design an application that can detect plagiarism ( web based ) in all formats using Google search engine API.
  what are the resources that i would be requiring for such an application. 
  Basically a user can upload a file and that file would be checked against various formats on the web . i have read that there are web crawlers but how exactly do we use them.
  Is Google search appliance API the correct approach?</p>
  
  <p>Also I have not used a Google API before so what would be the best way to start?</p>
  
  <p>Thanks a lot</p>
