Use the live search input for fast text search, using project key, name or issue key.
OR Filtering Syntax to include multiple keys or versions
Use the | character to search for multiple list items (similar to 'OR' statement in JQL).
For example "1.8|1.9|2" will return versions which contain 1.8, 1.9 or 2 strings including 2.0, 2.1, 2.2.2
JQL filtering on Epics & Versions panels
Find epics or versions using a component or label. Filter Epics & Versions panels using the main search bar or JQL statements.
Filters can be saved using the Save as... option and loaded from the filter list.
Private & shared filters for Epics & Versions panels
JQL search queries can be saved as private (visible only to the creator) or shared filters. For example, you can put your epics or versions into groups or a Scrum Master can prepare filters for the planning session.
Using the Filter Manager tool, you can export your Epics panel filters to any other backlog.
Lock Epics & Versions panels JQL filtering to the main filtering bar
JQL seems to be too complex for you? No worries. Use the board main search bar to filter EPICS panel using graphical drop-downs.
Once unlocked, the board's JQL will be copied to JQL panel. Then, you can continue to filter the EPICS panel separately.
Run JQL search directly on epics or on issues liked to epics
Change the JQL search mode on the epics panel. JQL query will be executed against epics or issues linked to epics.
For example you can find epics using component1 or find epics by issues using component 1.
