A system of one or more computing devices includes a user interface presented to a developer. A data store stores information identifying multiple functions, each corresponding to external functionality available from third party applications. The developer selects at least one of the functions to supplement functionality of a first application. A code generation module provides a software object for incorporation into the first application. The software object includes instructions for transmitting a query wrapper to a search system. The query wrapper includes a predefined text string corresponding to one of the functions selected by the developer. The software object includes instructions for receiving and displaying a result set including multiple items, each including a name and corresponding access mechanism of an application. The software object includes instructions for, in response to user selection of a first item, actuating the access mechanism to download or open the corresponding application.
