Can you use wildcards in a Fetch Function

I'm working on a flow to add a new deal in Zoho CRM. We sell courses. For this particular form, the person needs to have completed a different course to be able to move on. Only people who have completed the course will have a link to the form, but I would still like to check first.

My flow can fetch the Contact, so then I am looking for a deal that is Closed (Won) and the name CONTAINS a certain code (a three letter acronym we use).

Are there any wildcards that can be used in the fetch function?
