An internet search utility that combines and presents search results from disparate data sources to the user in a multi-view format. The search terms are disambiguated and a series of prioritized Views is displayed to the user in a View Mix interface. Each View includes a unique interface, processing widgets, and a unique combination of data sources. A View Picker determines, based on specific criteria, which Views are relevant and prioritizes the Views for the View Mix. As the user considers which View to select, the Pre-Caching Module conducts a background search, and preloads snapshots of top URLs for display. Selecting a particular View initiates a search per the instructions of that view. The resulting data is displayed in the View format. Views may be created by third parties or end users to reflect any particular preference thus yielding a multitude of unique views from which to consume search results.
