A search interface allows the selection between multiple presentation modes, including a default mode, a dense mode, a table mode, a command line mode and a research mode. In the research mode, two scrollable regions may be displayed side-by-side. In the first scrollable region, search results may be presented. In the second scrollable region, an aggregation of content extracted from documents associated with the search results may be presented. Selection of a search result may cause the presentation of a portion of the content aggregation in the second scrollable region with the content associated with the selected search result. Scrolling of the second scrollable region allows for a seamless transition from viewing the contents from one document to the contents of the next document associated with the search results.
