Build Your Own Search Engine
Submitted by Siddhartha Reddy (@sids) on Friday, 15 June 2012
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. I’ll go over what it would take to do that.
I plan to cover:
The basic idea of a Search Engine — 1.1 How is it different from a Database? — 1.2 Inverted Index
Techniques for constructing an Inverted Index — 2.1 Distributed Indexing — 2.2 Dynamic Indexing — 2.3 Index Compression
Scoring and Ranking
