Enhanced Search features several JQL functions not available as default in Jira, which are documented in the following sections:

Available Fields

Functions can be customised in many ways, and search a variety of fields in Jira. Make a request to the Jira Cloud REST API to see all fields you can use inside of the function expressions. For example, customfield_10024 or priority.id.



Most of the functions require a JQL 'subquery' as the starting point for the function you’ve selected. Providing an empty string (e.g. "") causes the query to match each issue in your Jira instance, making your query very inefficient.

User specific data is not supported in subqueries. So statements such as assignee - currentuser() are invalid.
