The Unmatched category contains many irrelevant tasks, how do I clean it up?
If you created very broad queries you could end up with thousands of tasks in your Unmatched containers. Other than clearing the workspace/.metadata/.mylyn/tasklist.xml.zip and workspace/.metadata/.mylyn/offline folder (note that this will entirely reset your Task List) the easiest option is to: • Clean up your queries to include only tasks of interest (note that including completed/resolved tasks is recommended). • Turn off Focus on Workweek in the Task List. • Delete all of the unneeded tasks from within the Unmatched containers. Note that if the tasks are not matched by queries they will be deleted permanently and any local notes or scheduling information that you have added to them will be lost.
