I've recently added a page to the Debian wiki,
<http://wiki.debian.org/BuildingAPackage>, that was based on
<http://wiki.debian.org/BuildingTutorial>. I created a new page
specifically so that it would turn up better in likely search results.
However, when searching page titles for 'build package', 'package
build',
'building package', and 'building', various other pages are returned
but
this page is not. I suspect that some search index is not being
updated
properly, because I can't see any other relevant difference between the
pages that are returned in the search results and this one.
