Similar Node

This module is meant to prevent duplicate content during the creation for nodes.

After typing in the title for the node and focusing on a different field it will run an ajax call that will find similarly named nodes in the same content type. It will then display the similar nodes with their respective link and a message explaining that the user should review those piece of content before posting their node because it might be duplicate content.

The user also has configuration options to select what content types they run on and how sensitive the comparison function is.

The comparison is based off a concept called Levenshtein distance
