No add those features. >I *like* that Lucene doesn't have a spider, or a file tree walker, etc >etc. It's conceptual simplicity.

I think its best if this were in a Lucene top level package... example org.apache.lucene.application.indexers.HTTPIndexer (which I think should be called Crawler). >In either event I think it's important to preserve Lucene's current >library interfaces.

The only thing I might suggest (which I've tested locally) is providing an AbstractDocument and making Document a default subclass. I tested this locally (and converting the referencing classes to use the abstract document to reference it) and it worked great. This might simplify adding document filters. Thats the only *change* I've suggested to the existing classes. But I tacked that on to the end as another option because I figured someone had a real good reason to make Document *final*. To reiterate, this does not seek to become the only interface to lucene. To draw a parallel: htDig has a htdig dev library. This seeks to add the features in another packages properly encapulated from the library except where new/useful features might be added that are more appropriate to the library.
