Hi,
After the switch to mediawiki in Fedora, we don't recommend page
hierarchies anymore. It is completely ignored by mediawiki in searches
unless it is a root page. Instead use categories which are fast and much
more efficient.
A few examples
https://fedoraproject.org/wiki/Category:Fonts_SIG
http://fedoraproject.org/wiki/PackageMaintainers
If someone has a few minutes, convert all the pages under
http://fedoraproject.org/wiki/India to use categories and organize
information as you can see above.
