3. Drupal Core Search
Cron.php Indexing process

4. Drupal Core Search
• HTML Tag Scores
• <H1> = 25
• <H2> = 18
• Accent Removal
• Montréal => Montreal
• Stemming
• skips, skipping = skip
Tip: Use porterstemmer to improve stemming in Drupal Core Search

5. Drupal Core Search
• SQL Not optimized for full text
search
• Limited Operators
• Slow and not scalable enough
• Stemming needs to happen in
the PHP side, not optimized
• Dead ends

• …
Apache Solr Search

• Separate Server
• Mathematical Indexing
• Fast!
• Replication / Solr Cloud
• Multiple indexes (Multicore)
• Which version to choose?
