Apache Lucene is a high performance, full-featured Information Retrieval library,
written in Java. Elasticsearch uses Lucene internally to build its state of the art distributed search and analytics capabilities.
Start small, but will grow with your business. It is
built to scale horizontally out of the box. As you need more capacity, just add more nodes, and let the cluster reorganize itself.
They will detect and remove failed nodes, and reorganize themselves.
A cluster can host multiple indices which can be queried
independently or as a group
Search comes with multi-language support, a powerful query language, support
for geolocation, context aware did-you-mean suggestions, autocomplete and search snippets.
None
Store complex real world entities in Elasticsearch as structured JSON
documents. All fields are indexed by default, and all the indices can be used in a single query, to return results at breath taking speed.
Toss it a JSON document and it will try to
detect the data structure, index the data and make it searchable.
Almost any action can be performed using a simple RESTful
API using JSON over HTTP. GET, POST, PUT, DELETE
