A Wide Area Information Server (WAIS) is a system that provides a means for searching and retrieving information from a large collection of data distributed across a wide area network (WAN), such as the internet. WAIS was developed in the early 1990s and is often associated with projects aimed at improving information retrieval for unstructured text databases.
