How do you use Elasticsearch?

Elasticsearch takes in unstructured data from different locations, stores and indexes it according to user-specified mapping (which can also be derived automatically from data), and makes it searchable. Its distributed architecture makes it possible to search and analyze huge volumes of data in near real time.
