I have just recently began looking at the search industry. From what I understand Google is considered by many as the best. But in the grander picture they only crawl less than 1% of the web and provide at most 50% relevance in their results. This shows that there is a lot of room for improvement (maybe $4B worth of work?).
I am searching for innovative search technologies beyond Google. Could anyone mention any startups or university research or places where I could find this?
