In the Web Portal you are able to search Active Jobs, Recurring Job Profiles, Completed jobs, and Deleted Jobs. 

To search for a job in the Web Portal > Jobs > View Jobs.

When searching for a Job in the Web Portal you can use the Smart Tables to customise and filter down your search. 

To search for a Job in the App in the Job tab, you can search for both Active Jobs and Completed Jobs, by selecting the tab inside the Jobs view.

When searching for Active Jobs, a User will only be able to see the jobs assigned to them or that are Queued.

When viewing Completed jobs, there is a filter option, where jobs can be filtered by dates, customers, and Users (which means jobs assigned to others can be viewed as well).
