How do I search Windows XP/2000 files by their summary meta-data?

I'd like to search for all files (not just office) for Title/Subject/Author/Category/Keywords or Comments which are all available on the Summary tab in Properties. The Windows XP built in search doesn't offer this (does it?). Is there a good 3rd party app to do this if XP can't do it natively? I know I can do an advanced "File Search" in the office apps, but only office files are searched. I want to check PDFs, JPGs, TXTs etc.
