watcher = currentUser() AND lastviewed >= startOfWeek(-1w) ORDER BY lastViewed DESC
I named this query, What I possibly worked on last week
The query actually searches for issues that I viewed so I still filter some manually but it's quite close to what I actually did because usually I mostly view what I work on not other issues that much.
If you have other suggestions for querying, I would like to see them so please let me know.
ACTUALLY you shouln't need this as Jira actually provides you a view for both last week and yesterday
