Slides for a talk I gave at The Fifth Elephant conference in 2012.
Description copied from the conference's website:
No, this is not another tutorial on using Solr/ElasticSearch/Sphinx/Lucene. Imagine that none of these existed and you need a search engine for your shiny new eCommerce startup. What would you do? Build your own search engine, of course. In this session at The Fifth Elephant 2012, Siddhartha Reddy describes what it takes to do that.
