How to organize a repository of regulatory documents with a search?

Question

CMS

Please let me know what are the options for the next task.
It is necessary to organize a repository of normative documents with a search in all texts. In general, we have clients who need up-to-date versions of regulatory documents, laws for a particular industry, and they do not want to bother with the search themselves, but want everything to be in one place. In short, such a normative reference search engine.
We will upload documents to the repository from Word files. Documents are grouped into categories. The client is given a login / password with access rights to materials of a certain category. It should be possible to set access to a specific validity period. The client enters via the web, drives into the search bar and receives a selection or searches manually for the library.
