Getting started with Elasticsearch, elasticsearch
Elasticsearch is a highly scalable open-source full-text search and analysis engine. It can store, search, and analyze large-scale data quickly and in near real time. It is generally used as the underlying engine/technology to provide powerful support for applications with complex search functions and requirements

Suppose we are creating an application similar to Weibo. Let's call it kiwi first. Kiwi is composed of messages. In kiwi, a message is called a ksay

If everything works, Elastic will run on the default port of 9200. At this point, open another command-line window, requesting the port, and you will get the description information.

Abstract: intends to write several elasticsearch use experience. First, start with the horizontal comparison of Elasticsearch and Sphinx. Cross-correlation is a good way to react to the pros and exposures of the problem. I am the Sphinx camp to the Elasticsearch camp, both are mature open source search engine, each has the pros and cons, this article can also be
