CONFIGURATION

• Enable Drupal module– Configure host, port, patch variables– Select content types, configure weight

sites• Hosting companies doesn’t support this

properly

• Sphinx is fast (makes craigslist’s search fly)• With sphinx you can run indexes as you want• With sphinx you will enjoy your time

optimizing MySQL queries• But if you need good and fast solution just go

with Solr
