How to search keywords in uploaded documents?
I have a web form where candidates upload their resume (pdf, doc, docx) and then are sent to my email as an attachment.

What I need is to filter those resumes before they are sent to me.
I only want to receive resumes from qualified candidates

I know this can be done with the Web form builder, but I just don't know how.

Any idea?
Someone can help me with this?
I will appreciate your help forever
Thanks in advance,
