I understand that you can search in Google Calendar that meet a search criteria that is a text (you can enter a "search text".

The search is then executed from a certain date/time and will return all events that meet the search text criteria.

The following amendments would make Search Event more powerful:
1. make it possible to search also for invited persons (not confirmed or confirmed etc), you might want to send an email (e.g. to ask why he has not confirmed, or send all confirmed invitees an updated agenda/documents etc)
2. make it possible to limit the search to a certain time window e.g. 7 days starting from the current date, so you can find the calendar event(s) for next week that meet the text/invitee search criteria
