Introduction

Since DSpace version 1.8.X. and greater, the search indexes are delivered via the "Discovery" facility using the SOLR service.

The Discovery Module enables faceted searching & browsing for your repository.

DSpace Discovery offers very powerful browse and search configurations that were only possible with code customization in the past.

With DSpace versions =>4.X Discovery is now the default.
