Abstract: A search system includes a memory storing application records that each corresponds to an application and includes data related to an attribute of the corresponding application. A processor executes instructions stored in the memory. The instructions include receiving a search query from a user device. The search query is based on a query string and indicates an application category and subcategory selected by a user of the user device via first and second rotational user interface elements. The instructions include identifying a list of application records according to the application category and subcategory. The instructions include ranking the list of application records based on number of downloads and matches between text data of the application record and the query string. The instructions include selecting a subset of the list of application records according to the ranking and transmitting search results to the user device based on the subset.

Abstract: A wheel-based user interface provides navigation between categories and subcategories of applications. A first browse wheel contains a plurality of category regions, each corresponding to an application category. In response to a user selection of an application category received at the first browse wheel, a second browse wheel is displayed. The second browse wheel contains a plurality of subcategory regions, each corresponding to an application subcategory within the selected application category. In response to a user selection of an application subcategory received at the second browse wheel, an application search query is generated using the selected category and subcategory.
