Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for indexing application pages of native applications that operate independent of a browser application on a user device. In one aspect, a method includes instantiating a virtual machine emulating an operating system of a user device; instantiating, within the virtual machine, a native application that generates application pages for display on a user device within the native application; accessing, within the virtual machine, application pages of the native application, and for each of the application pages: generating application page data describing content of the application page, the content described by the application page data including text that a user device displays on the application page when the user device displays the application page; and indexing the application page data for the native application in an index that is searchable by a search engine.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining when to implement native application that has been identified in response to a search query, the implementation occurring without user intervention. The implementation may involve installing and launching a native application on a user device in response to a query, or launching a native application already installed on a user device in response to the query.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for determining when to search a native application corpus for native applications and insert native application search results into a set of general web search results in response to receiving a query.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for scoring and ranking environmental views of particular content. In an aspect, a method determines, for each presentation mode of a content item, a presentation mode score for the presentation mode based on presentation mode signals, each presentation mode score being an indicator of quality of the presentation mode; selecting the presentation mode having presentation mode score indicating a highest quality relative to the quality indicated to the other presentation modes by the other presentation mode scores; and providing the search results to a user device for presentation according to the presentation order, each search result referencing a corresponding content item, and wherein the search result for the content item having the plurality of presentation modes is provided according to the selected presentation mode.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium for normalizing native application scores. In an aspect, a system ranks web resources and native applications based on web resource scores and normalized native application scores that are normalized to the web resource scores. The ranking is indicative of the relevance of each web resource and native application for a search operation relative to each other web resource and native application.
