I've been building prospect lists and noticed unexpected behavior with exclusions

I've been building prospect lists and noticed unexpected behavior with exclusions. I had "Recruit" in my "Job Titel contains" exclusion list, but results still included titles like "Operations / Recruitment." A few questions to understand how this works:

1. Do exclusions use substring matching like "Contains" does for includes? Or are exclusions exact word matching?
2. If exact word matching, do I need to list all variants separately? (e.g., "Recruit", "Recruiter", "Recruiting", "Recruitment")
3. What's the order of operations? Does the system first match on includes, then filter by excludes? Or something else?
4. Do special characters or slashes affect matching? For example, would "Recruitment" as an exclusion catch a title formatted as "Operations / Recruitment"?
5. Is there documentation on exclusion logic specifically? I found docs on the three include operators (Is similar to, Contains, Is exactly) but nothing on how exclusions work.
