Architecture - 2.7 Search Architecture

Question 1

What is Solr?

Answer 1

• An open source search platform. Right now, Magento EE natively integrates with this.
• There is some configuration needed.
• Fairly easy to set up and produces lightning fast and relevant results.
• (Solr is deprecated in Magento 2.1 and will not be supported in 2.2)
• Uses DSL-oriented interface

Question 2

What is Elasticsearch?

Answer 2

• Uses a JSON/REST API.
• Elasticsearch is more configurable on the fly.
• Elasticsearch supports complex nested types.
• If you want distributed indexing then you need to choose Elasticsearch. Elasticsearch is the only true option for cloud and distributed environments. Elasticsearch is scalable, lightning fast, and a breeze to integrate with. Its API is more intuitive and accessible than Solr’s.
