  { id: 2, name: 'Mechanical Keyboard', description: 'Durable keyboard with tactile feedback' },
  // Add more products as needed
];

// Add data to Meilisearch index
async function addData() {
  const index = client.index('products');
  const response = await index.addDocuments(products);
  console.log(response);
}

addData();

Step 4: Implementing Search Functionality

// Search endpoint
app.get('/search', async (req, res) => {
  const query = req.query.q;
  try {
    const index = client.index('products');
    const searchResults = await index.search(query);
    res.json(searchResults.hits);
  } catch (error) {
    res.status(500).json({ error: error.message });
  }
});

// Start the server
app.listen(3000, () => {
  console.log('Server is running on port 3000');
});

Step 5: Testing the Search Feature

Run your application and test the search functionality.
