Today I would like to draw your attention to a really helpful article by Rittmanmead taking a deeper look under the covers at the Endeca MDEX engine; how it works, what's so different about it, and why that matters to customers. This will in particular be useful for the technical audience. The other articles in the Endeca Week series are equally useful for a wider audience.
