Requirements

Before attempting SOLR discovery setup please make sure the following are correct:

1. Tomcat is listening on TCP port 80.
2. The SOLR webapp is correctly published.

Introduction

Since DSpace version =>1.8.X, a new "Discovery" facility using the SOLR DB service was introduced.

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

"Discovery" offers new powerful browse and search options that were only possible with code customisations in the past.

PLEASE NOTE:
