The Module Index Search searches the CPAN packages index, which is the file 02packages.details.txt. This is the canonical mapping of module name to the latest authorized stable release of that module, maintained by PAUSE and used by CPAN installers when given a module to install.
The Permissions Search searches the PAUSE
permissions database, which is the file
06perms.txt. This is the listing of
authors that can upload new stable releases of a module and have it indexed,
and that can modify the permissions for that module name. The first-come
permission, granted to the first user to upload a module name, has ultimate
authority on the name, and can add or remove any other user’s permissions. The
permission manager permission can add or remove other co-maint permissions.
The co-maint permission can only remove their own permission. Note that these
module permissions are not hierarchical. An author must have permissions
for each individual module name they wish to have indexed.
The Author Search searches the CPAN authors database, which is the file 00whois.xml. This contains public details of the PAUSE accounts.
See the API documentation for details.
