Maybe my question is not clear. We are looking for some system which can search the full text of the deposited documents; these are licensed materials, so we'll also need access restriction.
We use DSpace, but I don't think DSpace does full text search, e.g. it doesn't search content in bitstreams (pdfs, ppts...). 

Any suggestion?
Thanks!
Sophie

I would think DSpace, Fedora, and Eprint. DSpace is fairly easy to implement, which has embargo support in 1.6 (https://wiki.duraspace.org/display/DSTEST/Embargo ).
I have an article comparing DSpace and Fedora, but was written 6 years ago. DSpace has not been changed much, but Fedora is a different story.

Hello, list,
Do you know the Digital Library systems which can search within the documents (e.g. PDFs) and handle access restrictions (e.g. DRM)?
Has any of you compared these DL systems?

Thanks for any information!
Sophie
