Tips: With "Contains" filter, you can use '%' as wildcard (don't use other characters as wildcard, such as *, +, etc).
For example: Search By = Description; Filter = Contains; Search Term = Purch%Order,
will display "Define Purchase Order Types" and "Define Account Assignment Category for Asset Purch. Orders" activities.
If you want to search '%' in t-code/description/program, you can use escape character '\' before the '%'.
For example: Search By = T-code; Filter = Contains; Search Term = \%,
will display "MC1%" activity.
