There are several situations in which two or more users jointly search for online information. In such cases, typically the search sessions of the users are completely independent of each other even though the users are engaged in a joint search task. Such independent and disjoint operation of a task being performed simultaneously by multiple users fails to leverage the collaborative nature of the joint online information search to provide improved user experience (UX) and result quality. This disclosure describes mechanisms for improving the UX, search quality, and search effectiveness for such tasks. The search sessions of the users are connected to each other upon obtaining permission from the users. The search platform then retrieves and delivers search results to each of the users based on the collective queries and query histories of other users whose sessions are connected.
