knuru - yet another natural language search engine

I once introduced a natural language image search engine from Japan. This one is not for image searching, but a web page search engine, which also uses natural language for searching. To be honest, I've always felt that there isn't much difference between natural language search engines and regular ones. It's just that natural language search engines might be more intelligent. For example, if you search for pink flowers that bloom in spring, using a natural language search engine would likely yield results like cherry blossoms.
