The invention discloses a proximity search system. The system receives a search query from a first user to search for a second user. The system then identifies one or more candidate users in proximity to the first user. Further, the system transmits a proximity token to the respective client devices of the one or more candidate users. The system further causes the client devices to broadcast the proximity token. The system then determines that the first user’s client device detects the proximity token broadcasted by a second user’s client device. The system provides the first user with search results that include the second user.
