Methods, systems, and apparatus, including computer program products, for processing search results. A first query suggestion for a search query input is received, and a first set of image search results responsive to the query suggestion is received. Both are provided to a user device in response to the search query input. After providing the first set of image search results to the user device, a signal of user interest is detected in either of the query suggestion or at least one of the image search results. The detection is prior to receiving another search query input subsequent to the search query input. In response to the detection, a second set of image search results is provided to the user device to supplement the first set of image search results previously provided to the user device. The second set of image search results are responsive to the query suggestion.
