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

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

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

The Community influence • drunkenmonkey

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?

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.
