Cross-domain information management

A non-transitory machine-readable storage medium comprising instructions that upon execution cause a computing device to:

• receive, via a browser that renders first content provided by a first domain in response to a first query from a user, a user selection of a first type of information that the user selected for sharing with a second domain;
• include a user identifier of the user, a domain identifier of the first domain, and the first type of information in a cross-domain sharing specification;
• in response to a second query from the user for content of the second domain, access the cross-domain sharing specification to identify a respective user interaction information to send to the second domain;
• send, to the second domain, the respective user interaction information, to cause the second domain to produce a search result for the second query based on the respective user interaction information;
• and
• receive, from the second domain, the search result based on the respective user interaction information.

A system comprising:

• a processor;
• and
• a non-transitory storage medium storing instruction executable on the processor to:
• render, via a browser of a client computing device, first content provided by a first domain in response to a first query from a user;
• receive, via the browser, a user selection that a first portion of the first content is selected by the user to enable cross-domain sharing of a first type of information, wherein the first type of information corresponds to the first portion of the first content;
• store, in a cross-domain sharing specification, the first type of information by associating the first type of information with a user identifier of the user and a domain identifier of the first domain;
• obtain first information about user interaction of the user with the first domain relating to the first type of information;
• include the first information in the cross-domain sharing specification, wherein the first information is associated with the user identifier of the user, the domain identifier of the first domain, and the first type of information;
• in response to a second query from the user for content of a second domain different from the first domain, access the cross-domain sharing specification to identify a respective user interaction information to send to the second domain;
• send, to the second domain, the respective user interaction information, to cause the second domain to produce a search result for the second query based on the respective user interaction information;
• and
• receive, from the second domain, the search result based on the respective user interaction information.
