Where We Need To Provide

At configuration level, RRE needs to know where the following folders are located:

• configuration sets
• corpora
• ratings
• query templates

Although the RRE core itself requires these information, when it’s wrapped within a container defaults values are provided. For example, the Maven Plugin assumes the ${project.dir}/src/etc folder as the parent of all folders above.

As said at the very beginning of this section, if you created a project skeleton by means of the RRE Maven Archetype you will find all those directories with sample content and a README.

The picture below illustrates the folders structure; on the left a project which uses Apache Solr, on the right Elasticsearch.
