Want to add Search Capabilities to your website and don’t know where to start? Then Google AJAX Search API might be for you. The AJAX Search API provided by Google enables you to embed a search box into your web pages and display the results in your webpage in your own desired format and style. The perhaps nicest thing about utilizing the API is that it is free and does not require an account unlike Google’s Site Search that costs a minimum of $100 a year. However if you do sign up then if errors are encountered while retrieving your search results Google has the ability to notify you so that the issue can be resolved.
To get started Google provides documentation, examples, and even a code playground that has multiple examples that you can customize in place to view the results.
