This information is held in the Activity table and not searchable under Regarding field (English version) like Contacts etc although once the Activity has been completed you can search under History List.
You can change individual Activity by highlighting and selecting Reschedule Activity
UPDATE - I reminded myself that using the Global search facility would enable you to select Activity and then search for a word match if that is any use to you.

You cannot search this field directly but you can search it using Universal Search.
The name of the field is hard coded and not able to be changed.
Here is how to use Universal Search
