These are not recently completed tasks (don't know what counts as recently completed, but I'm pretty sure six months ago doesn't count), so I don't think it's relevant that they don't show when I turn off that filter.
These tasks do show on my calendar as completed, but they do not show in the search. I want to use the search because that's much easier than clicking though every single day on a calendar for the last six months.
Don't understand what you mean about history being limited to 1 week. I can see much farther back than that in the calendar.
I need to report on my completed tasks for the last six months to my supervisor, so I did a search with two rules:
Folder is WTS and IWALK
Date Completed is after May 31 2008
The search returned only 1 task -- the last one I completed -- even though there are dozens that were completed in that time period. I've noticed this same problem before, but am just now reporting it. Can you help me figure out if I am doing something wrong or if it is a bug?
