Simultaneously query common search engines and compile results into an interactive book with chapters, an index and pages.
Chapters are clusters of related pages. The pages are the search results. The index is automatically built from the pages.
Marking an index word automatically sorts all pages according to their relevance to that index word. The pages of interest can be found without having to scan through the entire list of pages.
Marking an interesting page also sorts all pages according to their relevance to the marked page. Whenever an index word or page is marked, the relevance of all other index words and pages immediately updated.
