At Google’s Searchology event, the company declared realtime search as its biggest challenge. Meanwhile, OneRiot released the first realtime search engine that crawls and indexes content behind links shared on Twitter, Digg and the wider social web (filtering out spam/noise to deliver signal).

OneRiot allows people to find the most reliable, socially-relevant blogs, videos and articles being shared right now from across the web. Filter out spam and conversational noise to deliver the fresh, reliable and relevant search results. In essence, OneRiot does for the social web what Google does for the static web.

“The potential of realtime search reaches far beyond the conversation stream around a keyword,” says Tobias Peggs, general manager at OneRiot. “By digging, tweeting or sharing links to webpages, people are signaling that the content on those pages is relevant to them right now. OneRiot takes those signals, indexes the webpage content, and returns that information in our search results in realtime.”

OneRiot also filters for spam and de-duplicates links shared through Bit.ly, TinyURL, Tr.im and other URL shortening services. This makes its search results not only realtime but also reliable. “We help users find socially-relevant content, filtering out the spam and noise,” said Peggs.

Additionally, new advanced OneRiot search features include :

• Domain Buzz Query – Search for a specific domain name (e.g. www.CNN.com) to determine what articles/posts from that publisher/blog have the most social relevance right now.
• Page Buzz Query – Search for a specific URL (e.g. a blog post) to find how many times that link has been dugg, tweeted or shared on the social web.
• First Shared Identifier – Learn who was first to share a particular link on the social web, and see their Twitter or Digg profile.
• Expandable Conversations – See what people are saying about a particular search result, and engage in a specific conversation around content.
• Results Page Filters – View OneRiot search results by “Realtime” or by “Pulse” – the company’s proprietary score of current social relevance.
