Google Calendar - Search for events using the Query to find those with certain text in the Summary field

I need to search in a google calendar for events from a date where the summary field contains certain text.
I can return all the events from a date but I don’t know how to format the Query string to search for text in the Summary field of the events.
An example is I want all the events from today onwards returned where the Summary field contains Available - Levin

This is what I have tried but I don’t get any events returned I do have at least one that should be returned

Looks like that field only accepts a free text search, just like the one in Google Calendar.

So what you can do is return all the results and filter by the Summary property.
