Search for duplicate or similar node titles when creating content? Much in the same way that it is on this site (as you type your question, it shows similar questions) is there a module that will search for similar nodes as I type the node title in Drupal?

I know of the Unique Field module, however it only checks after the node has been submitted. I need some way of doing it as they type.
There is module Uniqueness , it does exactly what you want. It allows you to enable for any content type, and you can configure checking on node add or edit or both.


  Uniqueness module provides a way to avoid duplicate content on your
  site by informing a user about similar or related content during
  creation of a new post. A UI widget is added to the node/add form that
  does asynchronous searches on inputted fields (like the node title or
  vocabularies) and returns the titles of similar content.
