Abstract: A computer-implemented method is disclosed. The method includes: obtaining search results in response to a search query initiated via a graphical user interface on a computing device; displaying, on the graphical user interface, a first subset of the search results; obtaining user engagement data representing user interaction with the first subset of the search results via the graphical user interface; determining a second subset of the search results including only search result items that are not included in the first subset; and causing search result items of the second subset to be displayed on the graphical user interface in a display order that is based on the user engagement data.

Abstract: An overview mode is used to navigate content. While in the overview mode, content is displayed as thumbnails such that a user may more easily locate content. A document map may also be displayed with a display of thumbnails while in the overview mode. The document map displays an outline of the content that includes selectable elements to assist in navigating the content. The number of thumbnails displayed may change while in the overview mode (e.g. receiving a pinch/stretch gesture). The thumbnails displayed may also be adjusted (e.g. up/down/left/right) using gestures (e.g. drag, swipe . . . ). A drill down view displays an expanded view of content on a thumbnail in response to receiving a drill down instruction (e.g. a tap and hold gesture on a thumbnail). A thumbnail may also be selected (e.g. tapped) to return to the original viewing mode and to display the content of the selected thumbnail.
