In Jira system, when user resolve an issue "Resolved" is updated with the current time, if this issue is colsed, "Resolved" is updated again.

It seems Jira uses "Resolved" filed to record the time when an issue is resolved and also is colsed. So it is impossible to find issues that just be resolved during week.

1. if we just calculate issue with Status="resolved" and "Resolved" filed within one week, issues had been resolved and closed will be missed. -> wrong

2. if we calculate issue with Status in ("resolved", "closed") and "Resolved" filed within one week, issues just be closed in this week will be calculated here. -> wrong

In my opinion, there should be a new field Colsed to record the time the issue is closed, and "Resolved" can only be updated when a issue is resolved.

It sounds like people are entering or changing the resolution as they go through the Resolved -> Closed transition in your workflow. Possibly by post-function? The resolution date really is just "the last time resolution changed from to <not null>"

I'm not sure a "closed" date is of much use - I've got workflows that don't even have "closed", it would be better to stick with "resolved" and look closely at how you're using it.
