Session: http://leuven2015.drupalcamp.be/sessions/state-search-solr-and-facets-drupal-8 Presenters: Nick Veenhof & Joris Vercammen Description: In this session I'll give you an overview what changed so far in Drupal 8 in regards to the Search eco-system. We will talk about Search API, Apache Solr, Facet API and Elastic Search. Over the course of the last 3 years I've been involved in how Search in Drupal 8 should take form and what needed to change to merge the Apache Solr module with the Search API Solr module. In this presentation I hope to give you some guidance what is still pending and what already was done. I will also try to explain what effort it takes to push and move such projects. Depending on the audience we can go really in-depth or stay general. Please let me know in advance what you expect from this session so I can tailor it to your needs!

4. Overview
• Created 2010 (for Drupal 7)
• Based on suggestions for Core Search
• Generic and flexible search tools
• Different data
• Different search engines
• Different types of user interfaces

5. The Big Merge
• 3 years in the making
• Crowdfunding campaign
• Drupal Dev Days & Drupalcon sprints
• Dedicated Sprint
• Google Summer of Code
• Lots and lots of tests
• Apache Solr for Drupal 7 stays
• Apache Solr for Drupal 6 is dead

6. The Drupal.org influence
• Issue queues in Drupal 8 are powered with Search
API Drupal 7 using the MySQL backend.
• Lots of optimizations happened due to this
adoption
• MySQL Backend more stable

9. Basic Architecture
• Search index
• Generic information
• Search what?
• Search server
• Actual storage/retrieval
• Can use database, Solr, etc.
• Search how?
• Views / Search API Pages
• Search Display?

10. Index items immediately
• Pro
• No stale data
• Security concerns
• User experience
• Contra
• Performance. Batch updating is messy.
• Not using tracking table.
• Takes longer before result is searchable.
• Inconsistent data with Solr Replication vs
Solrcloud.

Basic Usage of Search API

12. Solr
• Search API Solr with Solr 5
• Works natively with Search API.
• Tip: Use index Rendered Item with a view mode

13. Basic Usage of Search API
Solr

14. What still needs to happen?
• Simplified UI
• More Views-like UI for “Fields”
• Wizard for easy search creation (Think Views)
• Indexing performance
• Caching
• Operators
• Solr
• Multi-site searching proof of concept across
Drupal 7 and Drupal 8 (Apachesolr + Search
API)

15. What’s more?
• Search API
• Alpha 9 Release
• Facet API
• Working Development version
• Search API Page
• Alpha Release
• Search API Solr
• Working Development Release
• Elastic Search
• Working Development version

16. Facet api
