In order to improve common queries and other searches, Microsoft would want to enlist the help of humans – and this particular product has been rumored to be known as Distill, although it remains to be seen whether Distill is just the codename at the moment, and the final product will be called something else.
Distill intends to take common and complex queries before presenting them to users so that they can answer the question. The user will go ahead to provide the relevant result, which in turn can then be integrated in Bing results. All answers will be vetted in order to maintain a semblance of accuracy and relevancy, although it remains to be seen just how Microsoft intends to draw users to have them answer questions so that the engine can be improved.
