Get contacts by emails /api/contacts

My Mautic version is: v3.2.4
My PHP version is: 7.3.30
My Database type and version is: MySQL version N/A

My problem is:
I am trying to get a list of contacts by their emails from the REST API (using python). The endpoint in the documentation that seemed most relevant was here: Mautic Developer Documentation. Under Advanced filtering, there seemed like what I needed only switching phone to email in the query.

All variations that I have tried using where and search parameters haven’t worked as expected. It usually returns 0 contacts when I can visually verify they exist on the website.
