several former discussions* about that which confusing me, so I asked for myself:
I modelled some new metadata for documents stored in CS (using a new model) . Now I want to use a query from within a LC process to search for all documents stored in CS and have the same metadata (e.q. custom_id=12345).
So, how to do that? Can I use REST/web scripts for that (á la http://<host>:<port>/contentspace/service/index/all.mediawiki)
