Utilize a PDF's contained text to identify a document.

Hello,
Are there any tactics or suggestions I can use to automate the naming of a PDF file using its contained text? I have a few attendance certificates, for instance. I would like to rename the certificates using the name of the course rather than naming them certificate 1, certificate 2, certificate x.
Thanks in advance for your advice!
