Collaborative search results

A computer-implemented method comprising:

• receiving, from a first user associated with a first user device, a submission of a first alternative search result for a first query submitted by the first user, wherein an alternative search result is a search result that is submitted by a user of a search engine to be provided to other users of the search engine as an alternative search result, wherein the submission specifies a subpopulation of users of the search engine to which the first alternative search result will be available;
• associating the first query with the first alternative search result;
• receiving a second query submitted from a second user device by a second user different from the first user;
• obtaining, from the search engine, second search results responsive to the second query;
• determining that the first query matches the second query and that the second user is in the subpopulation of users specified by the submission of the first user;
• in response to the determining, generating a search results page that includes the first alternative search result in addition to one or more of the second search results;
• and
• providing the search results page to the second user device for presentation to the second user.

A system comprising:

• one or more computers and one or more storage devices storing instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
• receiving, from a first user associated with a first user device, a submission of a first alternative search result for a first query submitted by the first user, wherein an alternative search result is a search result that is submitted by a user of a search engine to be provided to other users of the search engine as an alternative search result, wherein the submission specifies a subpopulation of users of the search engine to which the first alternative search result will be available;
• associating the first query with the first alternative search result;
• receiving a second query submitted from a second user device by a second user different from the first user;
• obtaining, from the search engine, second search results responsive to the second query;
• determining that the first query matches the second query and that the second user is in the subpopulation of users specified by the submission of the first user;
• in response to the determining, generating a search results page that includes the first alternative search result in addition to one or more of the second search results;
• and
• providing the search results page to the second user device for presentation to the second user.

A computer program product, encoded on one or more non-transitory computer storage media, comprising instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:

• receiving, from a first user associated with a first user device, a submission of a first alternative search result for a first query submitted by the first user, wherein an alternative search result is a search result that is submitted by a user of a search engine to be provided to other users of the search engine as an alternative search result, wherein the submission specifies a subpopulation of users of the search engine to which the first alternative search result will be available;
• associating the first query with the first alternative search result;
• receiving a second query submitted from a second user device by a second user different from the first user;
• obtaining, from the search engine, second search results responsive to the second query;
• determining that the first query matches the second query and that the second user is in the subpopulation of users specified by the submission of the first user;
• in response to the determining, generating a search results page that includes the first alternative search result in addition to one or more of the second search results;
• and
• providing the search results page to the second user device for presentation to the second user.
