Creating a Search Engine - community.ez.no

Friday 24 July 2009 4:12:36 am - 3 replies

Introduction

On a big website or intranet, retrieving relevant content is key to site usability. In addition to a navigation structure based on the document hierarchy, most large sites have an internal search engine that accesses indexed content. In this article we look at the challenges involved with creating an internal search engine. This article is also an overview of the current research at eZ Systems in this area. As part of a research project, I have evaluated different relevance-based ranking concepts and have written a basic test implementation using different approaches.
