How to display all closed tasks in the project?

Question

Hello!

I have a question - how to display all of the closed tasks in project? For some reason Jira Product Owners decided that closed tasks are not useful and they just dissapear...but it is quite useful to have a look what has been done already and by whom and when...

So to be specific (as I know it night be not clear):

1) I would like to see all closed tasks (user stories and bugs) within the project

2) all of them per project means not per single sprint but all closed sprints (not tasks per current sprint! This I can see on the Sprint Board)

I was trying to google JQL but there is no working solution so far. I tried:

' project = "My project" AND closedSprints() ' which causes an error

' project = "My project" AND Sprint = "Sprint 1" AND closedSprints() ' - which causes an error

Issue solved - Issues browsing is not active by default due to unknown reason. Need to go to Project Settings -> Features -> and activate "Issue Navigator". After that there would be "Issues" displayed in the project left side menu where you can filter all issues.
