ElasticSearch is a great open-source search tool that’s built on Lucene (like SOLR) but is natively JSON + RESTful. Its been used quite a bit at the Open Knowledge Foundation over the last few years. Plus, as its easy to setup locally its an attractive option for digging into data on your local machine. The post will demonstrate how to install ElasticSearch on Linux.
