Abstract
Methods, articles of manufacture, and systems for searching collections of data using context sensitive expanded term searching are provided. The collection of data may be a relational database, text document, or any other type of searchable collection of data. In either case, a query including a search condition based on a specified search term may be modified to include additional conditions based on a set of expanded (e.g., conceptually-related) search terms. For some embodiments, a user may be given the ability to control the level of expansion and the context in which the terms may be expanded.
