Query Google Search Results as a MySQL Database in Node.js

Execute MySQL queries against Google Search results from Node.js.

You can use the CData Cloud Hub to query Google Search results through a MySQL interface. Follow the procedure below to create a virtual database for Google Search in the Cloud Hub and start querying using Node.js.

The CData Cloud Hub provides a pure MySQL, cloud-to-cloud interface for Google Search, allowing you to easily query live Google Search results in Node.js — without replicating the data to a natively supported database. As you query data in Node.js, the CData Cloud Hub pushes all supported SQL operations (filters, JOINs, etc) directly to Google Search, leveraging server-side processing to quickly return Google Search results.

Create a Virtual MySQL Database for Google Search Results

CData Cloud Hub uses a straightforward, point-and-click interface to connect to data sources and generate APIs.

  1. Login to Cloud Hub and click Databases.
  2. Select "Google Search" from Available Data Sources.
  3. Enter the necessary authentication properties to connect to Google Search.

    To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.

    To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.

    To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.

  4. Click Test Database.
  5. Click Privileges -> Add and add the new user (or an existing user) with the appropriate permissions.

With the virtual database created, you are ready to connect to Google Search results from any MySQL client.

Query Google Search from Node.js

The following example shows how to define a connection and execute queries to Google Search with the MySQL module. You will need the following information:

  • Host name, or address, and port: The address of your instance of the Cloud Hub (myinstance.cdatacloud.net) and the port (3306)
  • Username and password: The username and password of a user you authorized on the Cloud Hub
  • Database name: The database you configured for Google Search (googlesearchdb)

Connect to Google Search results and start executing queries with the code below:

var mysql      = require('mysql');
var fs         = require('fs');
var connection = mysql.createConnection({
  host     : 'myinstance.cdatacloud.net',
  database : 'googlesearchdb',
  port	   : '3306',
  user     : 'admin',
  password : 'password',
  ssl      : {
    ca : fs.readFileSync('C:/certs/myCA.pem')
  }
});
connection.connect();
connection.query('SELECT * FROM VideoSearch', function(err, rows, fields) {
  if (err) throw err;
  console.log(rows);
});

connection.end();
