Hello everyone!

I am developing with Umbraco 6 and i find the experience pretty amazing :) So I have come to the point that I need to create a huge documents archive and I need to use the CMS. The issue is that I have additional properties for each file such as tags, owner, ect. And I need to be able to search among these. 

For searching I have been using http://fulltextsearch.codeplex.com/ so far.

I figured there are two possible approaches:

1. I create all files as page types with as many props as needed and use the search straigt away. But can one Umbraco site handle above 100 000 pages (by spec, I have at least 100 000 images already)?

2. I extend the media type : http://our.umbraco.org/forum/developers/extending-umbraco/13593-Pdf-Document-Media-Type and http://nishantwork.wordpress.com/2012/09/20/umbraco-how-to-create-custom-data-type-in-umbraco-using-c/ But can I use the fulltext search in the custom media types?

I wasn't able to answer neigher of my two questions and I am sking if anyone can help me make the right, according to Umbraco, decision?

Thank you very much!
