Nowadays websites can easily track & store user events such as queries, result clicks & purchases, then how to use this collective behavior to guide us for better search. In this talk, we will walk through several applications of those signal data analysis, such as spell checker, synonym detection, finding phrases & tail query rewriting. We will also demo how to generate those analytical results & use them to perform run time query rewriting by a system, which combines the power of a search engine (in our case Apache Solr) with the power of a fast distributed compute engine like Apache Spark, to bring data science into production.
