Search Result Categorization

A computer-implemented method comprising:

• receiving a search query from a client device;
• generating search results based on the search query;
• identifying a plurality of categories responsive to the search query when the number of the search results is greater than a threshold, wherein each search result is associated with at least one of the plurality of categories;
• scoring the categories for the search results;
• identifying a subset of the categories having a score that is above a threshold score;
• and
• transmitting the search results and the subset of categories to the client device with instructions to display each category of the subset of categories with search results that correspond to the category.

A system comprising:

• one or more computers;
• and
• one or more computer-readable mediums coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
• receiving a search query from a client device;
• generating a number of search results based on the search query;
• determining a category for each of the search results when the number of the search results is greater than a threshold;
• and
• providing the search results to the client device as a non-categorized ranked list when the number of search results is less than a threshold, and as a categorized ranked list when the number of search results is greater than the threshold.

A system comprising:

• one or more computers;
• and
• one or more computer-readable mediums coupled to the one or more computers having instructions stored thereon which, when executed by the one or more computers, cause the one or more computers to perform operations comprising:
• receiving a search query from a user of a client device;
• generating a number of search results based on the search query;
• categorizing the search results into one or more categories based on user information;
• and
• providing the categorized search results to the client device.
