Pseudocode: Implement Search Functionality in Responses Collection

Objective:

Implement a search feature that allows users to search for specific values in the responses collection. When a user clicks the search button or presses enter, the app should search the database for the value entered and return matching documents.

Steps:

1. Define the Search Route in the Backend

• Express Route Handler Example:

  const express = require('express');
  const router = express.Router();
  const Response = require('../models/responseModel');  // Assuming the schema is in `models/responseModel.js`
  
  // GET route to handle search queries
  router.get('/search', async (req, res) => {
      try {
          // 1. Capture the search query from the request query parameters.
          const searchQuery = req.query.q;
  
          // 2. If no search query is provided, return an error response.
          if (!searchQuery) {
              return res.status(400).json({ error: "Search query is required." });
          }
  
          // 3. Search the 'responses' collection for matching documents.
          // This example uses a case-insensitive partial match on the 'name', 'email', or 'message' fields.
          const searchResults = await Response.find({
              $or: [
                  { name: { $regex: searchQuery, $options: 'i' } },
                  { email: { $regex: searchQuery, $options: 'i' } },
                  { message: { $regex: searchQuery, $options: 'i' } }
              ]
          });
  
          // 4. Return the search results.
          res.status(200).json(searchResults);
  
      } catch (error) {
          // 5. Handle any errors.
          res.status(500).json({ error: "Server error. Please try again later." });
      }
  });
  
  module.exports = router;
