Find issues by fixed date

I need to find all issues that are fixed in a certain timeframe. I tried to achieve this with the "Due After" and "Due Before" fields, but without any luck (no issues were found).
What I need is a way to search for issues that were set to a certain workflow state in a certain timeframe (e.g. "fixed between 01/01/05 and 02/01/05" or "closed between 01/01/05 and 02/01/05")
