What algorithm is used to generate this structure? ( after I have uploaded deb packages to Nexus)

Hi! After I have uploaded deb packages to Nexus, a storage tree structure is created for the deb package. What algorithm is used to generate this structure, specifically in what order (architecture, package name, version, etc.)? I need a link to the official documentation. Exactly the link where it can be read. I have not found this information in the official documentation, unfortunately. I would be grateful if someone could help me. Thanks!
