What is Elasticsearch?

  • Tool for querying written words
  • A standalone database server, written in Java, that takes data in and stores it in a sophisticated format optimized for language based searches
  • Implemented with HTTP/JSON for requests
  • Restful API ---> friendly to Ruby

How does Elasticsearch work?

  • Elasticsearch is a piece of infrastructure built around Lucene’s Java libraries
  • A simple API 
  • Interoperation with non-Java/JVM languages
  • Can cluster and replicate

Well, then what is Lucene?

  • Java based
  • Dates to 1999!
  • Is the heart of Elasticsearch 
  • Widely considered best-of-breed in open-source search software but cumbersome to use directly
