Data Center version has Secured Work Logs functionality, which was implemented to make work logs invisible for everyone except a specific list of team members, who are permitted to track work logs, such as Team Leads or controllers with a custom role.
As worklogs are secured, they are stored and processed in a table of your database another way. Issues cannot be found by sending JQL requests, which contain standard JQL fields.
Custom JQL fields return all issues (with secured and public worklogs). Results are filtered according to Timesheet Builder permissions and Jira project permissions.
Custom JQL fields
There are three work log fields, which have custom analogue.
We have implemented these custom JQL fields, so that they have the same behavior and list of supported operators and functions as standard fields.
You can search for issues as you usually do, create a custom filter using the custom fields.
Search by worklog author

sWorklogAuthor = user1
