InfoSpace, a developer of metasearch products, has enhanced InfoSpace.com, a search engine. The company said that the upgrades include an improved web site design, the addition of real-time search content, and the ability to filter results by search engine provider.

The comprehensive search results on InfoSpace.com are compiled using the results provided by search engines including Google, Bing, Yahoo!, and Ask. InfoSpace.com’s metasearch technology distills the search results, to allow users understand which results were found on multiple search engines, and those that are exclusive to a single engine, the company said.

Reportedly, to complement this web search, real-time updates from the microblogging service Twitter are available as part of InfoSpace.com’s search results. InfoSpace.com users can search for a topic and get search results and tweets at the same time.

John Rodkin, new general manager of search at InfoSpace, said: “Internet users don’t have to choose one search engine over the other; InfoSpace.com offers the top results from all of the major search engines, and they can see what people are saying right now about their search topic on Twitter. With our meta-search technology and real-time search, there’s no better place to search on the Web than InfoSpace.com.”

As part of a business transaction and contract agreement in September 2007, the InfoSpace.com domain name was transferred to a former business partner and managed by them as a separate online directory business. The site was reclaimed by InfoSpace in May, when the company began the website’s overhaul, redesign and improvements.
