It is a process of seeking information to help the users who are unfamiliar to the domain of their search goal or have no idea how to achieve their goal. There exists several search systems which support exploratory search. In this rapidly developing field, there is a need to look at the achievements and tendencies in order to give a better angle to the future research works. This paper provides an overview of exploratory search systems and discusses the state of the art. We analyze these available systems based on features such as algorithms, result ranking, explanations, etc.
