Sharing and collaboration of search results in a travel search engine

A system comprising:

• one or more processors;
• and
• memory storing instructions that, when executed by the one or more processors, cause the system to:
• obtain, for a search session, a set of search results;
• create, for a first user, a first session state of the search session;
• create, for a second user, a second session state of the search session;
• cause a first presentation, at a first computing device associated with the first user, of the set of search results;
• cause a second presentation, at a second computing device associated with the second user, of the set of search results;
• based on receiving a first refinement of the first presentation of the set of search results, update the first session state based on the first refinement and not update the second session state based on the first refinement;
• and
• based on receiving a second refinement of the second presentation of the set of search results, update the second session state based on the second refinement and not update the first session state based on the second refinement.

A method comprising:

• obtaining, by a computing device and for a search session shared between a plurality of users, a set of search results;
• creating, for the plurality of users, a plurality of general search session states of the search session, wherein the plurality of general search session states each indicate the set of search results, and wherein each individual general search session state of the plurality of general search session states is respectively associated with a corresponding user of the plurality of users;
• creating a shared session state of the search session, wherein the shared session state indicates one or more search results of the set of search results that have been selected to share with the plurality of users;
• causing respective presentations, at a plurality of computing devices respectively associated with the plurality of users, of the set of search results, wherein the set of search results is presented, at each computing device of the plurality of computing devices, in a first portion of a graphical user interface of the computing device;
• and
• causing respective presentations, at the plurality of computing devices, of the one or more search results that have been selected to share with the plurality of users, wherein the one or more search results are presented, at each computing device of the plurality of computing devices, in a second portion of the graphical user interface that is separate from the first portion of the graphical user interface.
