## Features

- **Smart Search**: AI-powered semantic search with Cohere reranking
- **Equipment Catalog**: Browse manufacturers, equipment types, and models
- **Manual Discovery**: Find specific manuals by equipment specifications
- **Content Search**: Deep search within manual content
- **Web Search**: Integrated Google search via Perplexity AI
- **Interactive Results**: Browser-friendly artifacts for easy document access

## Installation

```bash
npm install
npm run build
```

## Configuration

| `TYPESENSE_PORT` | `--typesense-port` | Typesense server port |
| `TYPESENSE_PROTOCOL` | `--typesense-protocol` | Typesense protocol (http/https) |
| `TYPESENSE_API_KEY` | `--typesense-api-key` | Typesense API key |

### Optional Configuration

| Environment Variable | Command Line Argument | Description |
|---------------------|----------------------|-------------|
| `DB_NAME` | `--db-name` | MongoDB database name |
| `OPENAI_API_KEY` | `--openai-api-key` | OpenAI API key for LLM features |
| `COHERE_API_KEY` | `--cohere-api-key` | Cohere API key for search reranking |
| `PERPLEXITY_API_KEY` | `--perplexity-api-key` | Perplexity API key for web search |

## Usage Examples

### Using Environment Variables

```bash

export COHERE_API_KEY="your-cohere-api-key"
export PERPLEXITY_API_KEY="your-perplexity-api-key"

# Run the server
node dist/index.js
```

### Using Command Line Arguments

```bash
node dist/index.js \
  --mongo-uri "mongodb://localhost:27017" \
  --typesense-host "localhost" \
  --typesense-port "8108" \
  --typesense-protocol "http" \
  --typesense-api-key "your-typesense-api-key" \
  --cohere-api-key "your-cohere-api-key" \
  --perplexity-api-key "your-perplexity-api-key"
```

### Mixed Configuration

```bash
# Set some variables in environment
export MONGO_URI="mongodb://localhost:27017"
export TYPESENSE_HOST="localhost"

# Override others via command line
node dist/index.js \
  --typesense-port "8108" \
  --typesense-protocol "https" \
  --typesense-api-key "your-typesense-api-key"
```
