Option to choose combination "and" or "or" using keyword search

Our customer uses the keyword option in report definitions.

To get more oppertunities using these keywords it would be helpful to install a possibility to change the search option for the keywords from „or“ (Default – the only oppertunity yet) to „and“ under "1 - Report Maintenance with PF9 - Find Report Definitions“ and under "5 - Active Reports>Folder Maintenance with LK (List active Reports by Keyword) "

Of course only if the performance is acceptable.
