Elasticsearch is open-source and NoSQL based distributed search engine which is written in JAVA.
It is designed for high-performance searches on large data.
For data storing it uses indexes which is the collection of different types of document and properties.
Compares to the relational database is very fast.
- A relational database consists of –
Databases -> Tables -> Row/Columns - But the Elasticsearch consists of –
Indices -> Types -> Documents with properties
To communicate with it requires REST APIs.
It is supported by various languages – JAVA, PHP, Python, JavaScript, Node.js and many others.
In this tutorial, I am using XAMPP for its installation.
Contents
1. Download

JAVA_HOMEenvironment variable. - Download Elasticsearch zip file from its Offical website.
2. Start

htdocsfolder e.g.htdocs\elasticsearch-5.6.3. - Now to start the Elasticsearch need to run the
elasticsearch.batfile using Command Prompt. - Open Command Prompt and navigate to the elasticsearch bin directory.
C:\>cd xampp\htdocs\elasticsearch-5.6.3\bin C:\xampp\htdocs\elasticsearch-5.6.3\bin>elasticsearch
- Now it is started.
3. Check
To check it is running or not open localhost:9200 in your browser.
You will see the similar type of output where it shows version details, tagline, etc.
4. Conclusion
It is better to use it when there is the huge number of data and require to retrieve data very fastly.
You have first need to run the elasticsearch.bat file if it is not running to starting working with Elasticsearch.
