Create your own Search Engine(Interface) using Google Custom Search API

Google Custom Search API are wonderful tools to create some awesome search engine like tools. Also if you want to add a search option to your website and customize the look and feel of your search results, Google Custom Search API serve best to you.

I have created a Real Time Search engine (I call it real time as it search as you type). I am really impressed by the speed/response of Google Search API.




The Code

I will show the code for one of the search api that I implemented in demo page. Let us see how to implement Web Search API.

Step 1: Generate Google Search API Key and Include JavaScript

In order to use Google Search API, you have to first generate a Key for you. Go to following page and signup your self for the Key.
Sign up for Google API Key

Next step is to include the Google Search API javascript. Don’t forget to mention your key in the below code.

Step 2: Add HTML Container for Web Search

We will create a textbox and a button that will take input for search. And a DIV that will be populated by results:

When user will write a query and push Search button, a request will be made to Google Search using Custom Search API and the results are fetched. These results are then copied into the DIV.

Step 3: JavaScript to call Google Search API

We will use following JavaScript to call the Google Search API and copy the results in our container DIV.
The code in plain english is:
1. Create an object to connect Google Web search using class
2. Set a callback function that will get call once the results for the search are fetched.
3. Call the execute() method with search query as argument.
4. In callback function, iterate through the results and copy it to container DIV.

var webSearch;
webSearch = new;
webSearch.setSearchCompleteCallback(this, webSearchComplete, [webSearch]);

function webSearchComplete (searcher, searchNum) {
	var contentDiv = document.getElementById('web-content');
	contentDiv.innerHTML = '';
    var results = searcher.results;

    var newResultsDiv = document.createElement('div'); = 'web-content';
    for (var i = 0; i < results.length; i++) {
      var result = results[i];

	  var resultHTML = '
'; resultHTML += '' + result.titleNoFormatting + '
' + result.content + '
'; newResultsDiv.innerHTML += resultHTML; } contentDiv.appendChild(newResultsDiv); } function search(query) { webSearch.execute(query); }

    jQuery is in use, you can still optimize and compact your code by utilizing it.

    • Viral Patel 30 October, 2009, 18:57

      @dharmesh, Thanks for the comment

      @vikas, yes sir.. I am using jQuery but I dont know why. I may became lazy to do document.getElementById() instead of $(‘#’). Yes I think there is still scope left in this example. :)

  • Nilesh 30 October, 2009, 19:51

    The search API has been depreciated and hence I think your implementation doesn’t work now. But that’s a great implementation. Would you be willing to write it using the current custom search api?
