You are only shown the parts that are yours
The manual is filtered by the same permissions as the product. A person whose group has no Shop sees no shop guide; the developer reference needs developer access; a tool you have not bought is not described to you.
The part worth saying out loud is that the search is filtered too, against the source rather than the rendered page. Gating only what is displayed leaves a search box that will happily quote you two paragraphs of a document you are not allowed to open — which is not a documentation feature, it is a disclosure.
