I want to thank folks for their responses to my question.
I was suspecting false negatives might be a problem, too.

If y'all have more to share on plagiarism software in general, I'm happy to hear more. I may want to build some ammunition to take to our IT people.
Thanks!

I am not a fan of any of the well-known commercial anti-plagiarism packages because I can generate both false positives and false negatives easily.

One semester, I offered extra-credit in a couple of classes to students who could sneak plagiarised material past a commercial package and show me how they did it. More than 80% of the students in the classes could do so and several students showed me more than 1 way.

(We were testing the product for adoption. I am amazed that schools are buying these services without testing. Instead, schools seem to rely on sales pitches and testimonials.)

Finally, many cases of plagiarism are done by very lazy students. Doing Google searches on suspicious phrases often produces the copied document on the first page of searches.
