Abstract: A computer-implemented method, system and computer program product for improving the quality of subsequent searches. A request is received from a user to perform a search using the term(s) provided by the user. A search is then performed using the provided term(s). A representation of the search result is depicted as an area (e.g., bubble) with terms of interest displayed outside the area. The area represents a set of documents that were found in the performed search and the terms of interest represent terms that may be of interest to the user based on this set of documents. These terms of interest may be selected by the user to adjust the search result. In this manner, the user is presented with an intuitive view as to how different terms or different searches will have an impact on the search results thereby improving the quality of subsequent searches.
