How to delete / update a document using lucene?

Question

I am creating a tag system for my site

I have the basics of adding a document to lucene, but I can figure out how to delete a document or update it when the user changes the tags of something. I found pages that speak using the document index, and I need to optimize to effect, but how do I get the document index? I also saw another who said to use IndexWriter to delete, but I could not figure out how to do this with this.

I am using C # asp.net and I do not have a java installation on this machine.
