Search suggestion and display environment

A system, comprising:

• a data processing apparatus;
• and
• a memory storage device storing instructions executable by the data processing apparatus and that upon such execution cause the data processing apparatus to perform operations comprising:
• receiving, in response to a search query for resources received from a user device, a set of search query suggestions, each search query suggestion being based on the search query and different from the search query;
• for each search query suggestion, receiving data identifying a respective set of images determined to be responsive to the search query suggestion;
• for each respective set of images, generating a representative image set depicting a subset of the respective set of images determined to be responsive to the search query suggestion;
• determining that a particular source of images determined to be responsive to one or more query suggestions has a diversity measure that meets a diversity threshold, where the diversity measure is a measure of a first number of images determined to be responsive to the query that are hosted by the particular source to a second number of images determined to be responsive to the query that are hosted by the particular source and other sources, and in response:
• generating a representative image set that depicts a subset of images hosted by the particular source;
• providing to the user device, in response the search query, a search results page resource, the search results page resource including instructions that cause the user device to render a search results page that includes:
• a set of search results that identify images that are determined to be responsive to the search query;
• for each search query suggestion, a search query suggestion grouping including:
• data describing the search query suggestion;
• data depicting the representative image set;
• and
• data depicting the representative image set that depicts a subset of images hosted by the particular source.
