Real-time search is

Real-time search is a fast-growing area that digs up results based on what people are saying or publishing right now. Companies like OneRiot, Topsy and Scoopler scour through sources like Twitter, Digg and Flickr to find out what users are sharing at the moment.

Boulder, Colorado-based OneRiot is one of many real-time search startups, and it's launching a Developer Network today that builds off the release of its application programming interface (API) in July. It has about 40 partners who are incorporating OneRiot search results in one way or another into their projects. A couple are Gioo, which pools results from many search engines, and Clipta, a video search engine.

OneRiot says it factors in 26 different pieces of criteria in its search engine, including a link’s freshness, its domain authority or how reputable the Web site is, and velocity or the speed at which a link is shared through the community.

The company recently added another $7 million in investment from existing investors Appian Ventures, Commonwealth Capital Ventures, and Spark Capital.
