+# Gin Full-Text Search with Typesense
+
+A RESTful search API built with Go Gin framework and Typesense, featuring full-text search capabilities with environment-based configuration.
+
+## Tech Stack
+
+- Go 1.19+
+- Gin Web Framework
+- Typesense
+
+## Prerequisites
+
+- Go 1.19+ installed
+- Docker (for running Typesense locally). Alternatively, you can use a Typesense Cloud cluster.
+- Basic knowledge of Go and REST APIs.
+
+## Quick Start
+
+### 1. Clone the repository
+
+```bash
+git clone https://github.com/typesense/code-samples.git
+cd typesense-gin-full-text-search
+```
+
+### 2. Install dependencies
+
+```bash
+go mod download
+```
+
+### 3. Set up environment variables
+
+Create a `.env` file in the project root with the following content:
+
+```env
+# Server Configuration
+PORT=3000
+
+# Typesense Configuration
+TYPESENSE_HOST=localhost
+TYPESENSE_PORT=8108
+TYPESENSE_PROTOCOL=http
+TYPESENSE_API_KEY=xyz
+TYPESENSE_COLLECTION=books
+```
+
+### 4. Project Structure
+
+```text
+├── routes
+│   └── search.go
+├── utils
+│   ├── env.go
+│   └── typesense.go
+├── server.go
+├── go.mod
+└── .env
+```
+
+### 5. Start the development server
+
+**Standard mode:**
+
+```bash
+go run server.go
+```
+
+**Hot reload mode (recommended for development):**
+
+First, install CompileDaemon:
+
+```bash
+go install github.com/githubnemo/CompileDaemon@latest
+```
+
+Then run:
+
+```bash
+CompileDaemon --build="go build -o server ." --command="./server"
+```
+
+The server will automatically restart when you make changes to any Go file.
+
+Open [http://localhost:3000](http://localhost:3000) in your browser.
+
+### 6. Search API Endpoint
+
+**Search:**
+
+```bash
+GET /search?q=<query>
+```
+
+Example:
+
+```bash
+curl "http://localhost:3000/search?q=harry"
+```
+
+### 7. Deployment
+
+Set env variables to point the app to the Typesense Cluster:
+
+```env
+# Server Configuration
+PORT=3000
+
+# Typesense Configuration
+TYPESENSE_HOST=xxx.typesense.net
+TYPESENSE_PORT=443
+TYPESENSE_PROTOCOL=https
+TYPESENSE_API_KEY=your-production-api-key
+TYPESENSE_COLLECTION=books
+```
+
+- Configure CORS middleware for specific origins.
+- Configure gin to run in release mode.
+- Add some sort of authentication to the API.
+- Add rate limiting to the API.
