Re: [Clucene-perl] Questions about API compatibility with Document class

Thanks for the advice. I thought perhaps there was some design
decision that either made that function inaccessible or uncessary.

Most of what I need I can get via Document->toString() and some regexs
- however, it would be more convenient and probably safer to implement
the fields method from CLucene.
