I am wanting to search through a folder in Sharepoint to find a PDF that contains a given string, which in this case is a course (e.g. ECON 2000-100). I don't understand how to format the ODATA filter query in order to accomplish this. Here is a screenshot of my flow as well as some example documents of what I am searching for. The first part of the PDF names are blurred out to hide private information.
