Searchable File Server, Crawl/Index with a Web interface?

I've have an eSATA drive setup as a Network Share and it works great. I want to have a web interface to make its contents searchable, (Word Files, Text Files, PDF, etc.) I see a few open source applications that will do this, like Recoll, but is there anything that I can make work on OpenWRT on a WRT3200ACM? Something based on libextractor maybe? I have the eSATA drive setup as Extroot so application space isn't a problem. Suggestions?
