How to server a web request using hbase

I have about 3 million documents that are pdfs, docs and images. I have build a website and if user search from website interface, I have to serve those hbase stored documents as required.

How can I do it?

Is it good to use hbase for serving web documents (in future these documents will be further increased) ?

My hadoop version is 1.2.1 and hbase 0.94.
