In companies a large amount of information is maintained that is accessible via network communication tools. This makes searching for a particular piece of information a difficult task. We identified two major difficulties that are experienced using existing search engines. These difficulties are that many of the existing search engines only take syntactic information into account and therefore do not find all relevant documents, and that many of the retrieved documents do not contain relevant information.
