What is searchable and what is not in Case Studies for Construction & Evaluation?

I am wondering if it is typical to not be able to search room names, room numbers, and door numbers in the CE case studies. I have not passed twice now and I believe it would be a huge help for many if we were able to do so. I understand scanned images might not be searchable but Architectural drawings? Can anyone confirm if we can search the Architecture drawings for door numbers, room numbers, and room names? Thanks.
