[Zope] filename splitter

Hi, I don't usually do this but I need your advise on something. It's a filename splitter for a KeywordIndex of File objects. http://www.peterbe.com/plog/filename-splitter By applying this splitter I hope to be able to search for files by parts of the filename. Has anything like this been done before? Am I on the right track? Do you see any pitfalls? -- Peter Bengtsson, work www.fry-it.com home www.peterbe.com hobby www.issuetrackerproduct.com
