Pipl’s query-engine helps you find deep web pages that cannot be found on regular search engines. It’s designed to retrieve information from searchable databases and extract facts, contact details and other relevant information from personal profiles, member directories, scientific publications, court records and numerous other deep-web sources.

Pipl claims they’re “using advanced language-analysis and ranking algorithms to bring you the most relevant bits of information about a person in a single, easy-to-read results page”.

You can perform searches via “Name”, “Email”, “Username” and even “Phone” numbers.

I tried a quotation search for my name and the results were spot on.

Likes: Deep web search, fast search engine

Dislikes: Why no RSS feed? This way, I can subscribe to my feed in my Google Reader and be notified automatically of any updates.

Have you tried Pipl? I’m sure you’ll find decent results searching for your own name, but how about digging deep into a colleague or competitor’s name for some interesting intel?
