This is the second blog post of a series dedicated to the use of Solr search engine with Omeka S.
The first blog post was about the installation and the minimal configuration of Search and Solr modules. This time we will see how to configure facets.

It is important that the Solr field be multi-valued if you want to take into account all values of the “Subject” field and not only the first.
