Indexing and Searching Contents of Uploaded File

I have written a simple module that will index and search the contents of uploaded files (doc,xls,pdf,rtf and txt) using the very powerful and fast (IMHO) swish-e search engine (http://www.swish-e.org). This module requires swish-e and filters (for doc, xls, rtf and txt) programs installed in the server. I know, i know... this is not ideal in a shared environment where you dont have a total control of your server. This is ideal though in an intranet website (where you have control of your server) where a lot of documents uploading (manual, etc) happens.
If anyone out there interested, just say 'aye' :) and will try to upload this in CVS.
