Have you built an internal use case library/knowledge base for your CS team?

Hi all, 

I was wondering if anyone has built an internal customer use case library for their team?
The general idea here is to be able to pool knowledge of our global CS team into a searchable database (that can be used not only by CS but also benefit Sales, PS etc ).
Ideally, users could then search by customer industry, region, product type etc. and access ALL relevant use cases/customer stories, not just the public customer reference stories. 

If anyone has done this, I would love to hear how you approached this and what tools you used?

Thanks!
