Using Opensolr With Pantheon Sites
Learn how to create and configure Opensolr with Solr for advanced search indexing features for your Drupal sites.Discuss in our Forum Discuss in Slack
Apache Solr is a system for indexing and searching site content. Pantheon provides Apache Solr as a service that works well for the majority of sites on the platform. No permission or action is required from Pantheon to use Solr.
Currently, the version of Solr on Pantheon is Apache Solr v3.6.
However, if you are looking for additional features for more advanced use cases, you may want to consider an external Solr service.
The Opensolr service offers a number of features including:
- Smart full-text search
- Similarity search
- PDF and document search with opensolr Tika
- JTS Polygonal geo-spatial search
- REST-like API
This document covers Opensolr configuration for Drupal sites. For WordPress-Opensolr integration, see Opensolr's WPSolr Integration tutorial.
Before You Begin
Make sure you have already enabled:
- Drupal 7: the Apache Solr Search module
- Drupal (Latest Version): the Search API Solr module using Composer, which is required by Search API Solr to manage dependencies.
