The latest company to attempt to chip away at Google’s search dominance is getting quite a bit of attention.  Cuil, an engine that claims to return more search results than Google (120 billion pages, to be exact), was started by former Google engineer Anna Patterson and made its debut this week.  Cuil may be the most visible (for now), but there are a number of interesting search startups looking to challenge Google.  Here are a few of the standouts:

Mahalo

Optevi

Powerset (recently acquired by Microsoft)
