Solr Cores for Drupal 8, 9, 10, and 11

Solr compartmentalizes itself into cores (or collections if you're using SolrCloud). Each Solr core has its own directory, configuration, and set of search data. While a core can be thought of as an “index”, it is much more.

In this tutorial, we'll:

  • Identify the difference between a Solr core and an index.
  • List the various ways a core can be created.
  • Explain why Search API needs a custom core configuration.

By the end of this tutorial you should be able to explain what Solr cores are, and how to create a Solr core (or collection) that is compatible with Drupal's Search API module.
