The current implementation of ChaCha offers a combination of automation and people-powered search. The results can be organized by a vertical, like images or news. Also it has a set of related searches. But by far the most interesting and unusual aspect of ChaCha is its people-powered search.
ChaCha employs people to help users sift through the results. This is cleverly done using a familiar chat interface. When you first come to the site, you are presented with a standard search box. Type in a query and you get back a traditional list of matches. In the testing we did, we found both the performance and quality of the results to be quite good.
