I don’t think file comparison software is likely to be very helpful for your purpose.

If you can define the text patterns that you are looking for, even approximately, a good full text search program will allow you to search for them across multiple files and return both the number of hits and the files where the patterns occur.

File Locator Pro and dtSearch will both do that, but both require Windows. There may be Mac solutions available too, but I wouldn’t know about them.

If you want to analyze files to isolate text patterns that you might then want to search for, you should be looking at text mining software. There are many text mining systems targeted to the marketing research and legal professions, but they tend to be both very pricy and complex.
