Welcome to the Elasticsearch Guide! This document will help you understand the basics of Elasticsearch and how to leverage its power for search and data analysis. 🚀

What is Elasticsearch? 📦

Elasticsearch is a distributed, RESTful search and analytics engine that allows you to store, search, and analyze big volumes of data quickly and in real time. It's built on top of Apache Lucene and is widely used for log analysis, full-text search, and more. 🌍

Key Features

  • Real-time search: Instant query responses with full-text capabilities
  • Scalability: Easily scale horizontally to handle growing data
  • Distributed Architecture: Automatic sharding and replication for high availability
  • Flexible Query DSL: Powerful and expressive query language for complex searches

Getting Started 🧱

  1. Install Elasticsearch
    Download and install Elasticsearch from the official website
    ⚠️ Ensure you follow the installation guide for your operating system.

  2. Start the Server
    Run the command elasticsearch in your terminal to launch the server.
    📈 You can monitor the cluster health via the Kibana dashboard.

  3. Index Your Data
    Use the following example to index a sample document: 

    {
  "title": "Elasticsearch Basics",
  "content": "A guide to get started with Elasticsearch..."
}

    📁 Explore indexing in depth for advanced techniques.
