A pattern index can be created and used to searching for desired content in electronic databases. The pattern index can include a tuple pattern index containing separately identifiable and indexed tuple entries that are based on combinations of words within the electronic documents. The pattern index and other indexes can also be used in an incrementally graduating search to inherently apply order and priority to the search. Suggested terms and alternate terms, which are different than those that are provided by the user as part of a search request, can also be considered as part of the search and can be provided to the user for selection during the search to dynamically alter the scope of the search and to provide auto-complete functionality.
