Session Search
In addition to the My Work dialog, you can view a list of sessions and open a session from a drop-down list on the Session Manager tool.
Click the down arrow 
on the Session Manager tool to display
the session list.
Type in the Search box if you want to narrow down the display list. The search displays results that match a portion of the session’s name or the full name.
When you find the session you want, click the session name in the list to open it. If a session is currently open, you are prompted to save any edits, and the session closes before the new session opens.
Unlike the session search in Solution Center, when Session Manager searches for sessions, it is limiting its search only to sessions associated with the feature service used in the open project. It also limits its search to the tenant to which you are connected, and finally, limits to searching sessions that you have permissions to view on the My Work or Available Work tabs. Session Search is also looking for the version name that accompanies the session name, despite the version name not being visible within Session Manager. This is important in that a session search conducted in Solution Center could return different results (a different number of matches) than one conducted within Session Manager.
