Search is omnipresent these days, from the moment we type a set of keywords into our favourite search engine to find a webpage we are looking for to the moment we type a name and expect our email client to find all the emails sent by that person. Both these processes are based on years of research and experimentation in the field of Information Retrieval in order to efficiently being able to find the most relevant documents.
This blogpost will show how to set up Elasticsearch, one of the best and most popular search engines (with Solr being the other main alternative). Its main characteristic is to allow unbelievable scalability and advance querying and indexing capabilities with minimum engineering effort. In addition to this, I will also shown how to perform some basic operations using elastisch, a fantastic library for elasticsearch written in Clojure.
