Searches on the Document Review screen that result in very limited (or zero) results returned are usually being limited by search criteria.   Individuals who have been assigned multiple roles (e.g., Supervisor and Payroll Clerk) will be authorized to see specific users within the ranges assigned to each of those roles.  If you can see your supervisees as a Supervisor but every user in the system as a Payroll Clerk, then accidentally searching as a Supervisor would greatly reduce the number search results returned.

If your Default search (Search Description) has accidentally been saved or updated with previous search data, this can also limit your returned results.  Check both basic and advanced search options to see if that is the case.   Advanced Search options can be expanded by clicking on the [+] symbol next Show Advanced Search heading.   To reset your default search preferences remove any saved data (such as an Emp Number) and click the Save as Default button while on the Default search description.  Once updated, the Default search should return the maximum amount of records.

All settings on the Document Review screen can affect the search results and should be reviewed if difficulties are encountered.
