Keywords in event settings

Hi all,
A user reported to me that she is used to enter some keywords when she creates an event but she doesn’t know how to use them. She would search events based a specific keyword for example.
Could you help me please?
Regards,
Alberto

They are not used anywhere except in the page’s <meta> tag at the moment.

Have you planned to add a search features in the next releases? Is there any plugin to be activate to search into the events?
