Building Nutch: Open Source Search

ABSTRACT

Search engines are as critical to Internet use as any other part of the network infrastructure, but they differ from other components in two important ways. First, their internal workings are secret, unlike, say, the workings of the DNS (domain name system). Second, they hold political and cultural power, as users increasingly rely on them to navigate online content.

When so many rely on services whose internals are closely guarded, the possibilities for honest mistakes, let alone abuse, are worrisome. Further, keeping search-engine algorithms secret means that further advances in the area become less likely. Much relevant research is kept behind corporate walls, and useful methods remain largely unknown.
