Methods, systems, and apparatus, including computer programs encoded on computer storage media are provided. An example method includes receiving user input in a control, for example, one associated with a search engine. The user input includes a series of input characters that when completed would form a completed user request. The method further includes, while receiving the user input, evaluating the characters to identify completions for the completed request. The method further includes identifying, by one or more processors, a content item associated with the one or more completions and identifying display data associated with the content item for transmission to the user along with one or more completions in response to receiving the user input.
