For larger Drupal and WordPress websites, say tens of thousands of pages, the core search feature is not suitable. To handle high search volumes one should look to external third party search solutions. The most popular open source tool is Apache Solr.
Solr is the popular, blazing fast open source enterprise search platform from the Apache Lucene project. Its major features include powerful full-text search, hit highlighting, faceted search, dynamic clustering, database integration, and rich document (e.g., Word, PDF) handling. Solr is highly scalable, providing distributed search and index replication, and it powers the search and navigation features of many of the world's largest internet sites.
Here are some of the Apache Solr features on Drupion platform:
- Compatible with Drupal modules Search API Solr and Apache Solr search
- Compatible with WordPress plugin WPSOLR
- Unlimited Solr indexes
- Unlimited documents stored
- Unlimited queries
Apache Solr backend configured for Drupal and WordPress websites is maintained on all Drupion Cloud and Dedicated servers, so you can easily enable one of several Apache Solr search modules or plugins and disable core search indexing, which also helps to reduce load on database server.
