Keyword Matching on Exchange Online Source

Hi, let me try differently: My keywords would be project titles (e.g. "Falcon" or "Dreams") or company domains (@falcon.com or @dreamscompany.com).  In my Exchange source, i have the data columsn from emails and appointments, e.g. Title, From / To Fields, Participants or the Preview part of an email body. I want to check these columns against my keywords and have it return the corresponding value from the keyword table that matches the most of a given keyword. thus, identifying to which project / company a line item belongs most probably, rather than counting this manually at the end of a month.  does that make more sense?
