Benefits of having an Internal website search script:

  1. Faster information or product discovery can increase sales. (If your website search has a voice search feature, it also helps in delivering a much faster search experience).
  2. Spelling error tolerance: We cannot expect our site visitors to have a Ph.D. in English or any other language. So our search engine should be capable of smartly handling spelling errors.
  3. Type-ahead–  A dynamic search box that completes the search queries of the users without the user having to type entire search terms will save a lot of time in product discovery and improve user experience.
  4. Facets and filters– The option to filter search results by category in search can help users refine their search results and find products or content that they want to.
  5. Search analytics– The information about what your site users are able to search on your website lets you know what kind of content people are able interested in your website and helps you strategize on what products to stock on your site or what kind of content to write more of.

Internal website search script for any CMS:

If your site is based on any Content Management System (CMS), then the search functionality is handled by CMS by default. Usually, the default search functionality on any website is pretty basic and doesn’t have any desirable features like auto-complete, spell correct. Expertrec has a universal search function for all Content Management Systems (CMS) since it has an inbuilt crawler that crawls and indexes all websites irrespective of the CMS they are built on. As most CMS support plugins to enhance their functionality, a third-party or community-based plugin can be used for the search features. You can still implement a powerful custom site search provided by existing search engines like Google, Bing, etc. An internal site search for a static website is also possible and can be implemented easily. Additionally, you can also build search functionality from scratch.

  2. The name of your search engine will be automatically generated based on the URLs you select. You can change this name at any time.

Your basic search engine is ready to use! To see more configuration options, go to the Control Panel. Control Panel also has a preview window that allows you to test and fine-tune your search results.

  2. Sign in to Control Panel using your Google Account (get an account if you don’t have one).

Implementing Google search box

Once you’ve created your Programmable Search Engine, you can add the Programmable Search Element to your site. To do this, you’ll need to copy some code and paste it into your site’s HTML where you want your search engine to appear.

  1. In the Control Panel click the search engine you want to use.
  2. Click Setup in the sidebar, and then click the Basics tab.
  3. In the Details section, click Get code. Copy the code and paste it into your page’s HTML source code where you want the Google search bar to appear. Click on receive codeadd google search to website
  4. Add this code to your website. If you are on Word press, you can use a plugin called Elementor or insert headers and footers plugin that will do this for you. If you want exact placement, you will have to edit your theme file by going to Appearance-> theme editor. If you are on another CMS you can contact your developer and ask him to add it to all the pages where you want this search bar to be shown.autocompleteadd google search to website
  5. Once you add this code to your website, you will be able to see the Google search bar on your website pages.

Editing the look and feel

On many occasions, it makes sense to have a search box appear independently from search results. A two-column layout allows you to render a search box in one area of your page (for instance in the sidebar) and display results in a different one (for instance the main area of the page).

To change the layout of your engine go to the Look and feel section in the Control Panel and click the Layout tab. After selecting and saving the 2-column layout in the Control Panel, you also need to change the HTML code for the Search Element.

Enable Autocomplete

Apart from customizing colors, fonts, or link style in the Control Panel, it is possible to influence the look and feel and the behavior of the search box via custom HTML attributes.

This allows you to override some of the general settings from the Control Panel. It is especially useful when you want one search box (e.g. one on the homepage) to behave differently than other ones on the site. For example, you can enable or disable the autocomplete feature using attributes. By default, it is set to true if autocomplete is enabled in the Control Panel. By switching the value to false you can control how the element behaves.

<div class="gcse-searchbox"></div>
<div class="gcse-searchresults" data-defaultToImageSearch="true"></div>

Customizing Search Results

In a similar way to customizing the search box, you can add additional options to the search results element.

For example, in order to change our search engine from web results-based to image-based.

First of all, you need to enable Image Search in the Control Panel for your search engine. In the Setup section, in the Basics tab, click the Image search option into the “on” position. After that, add the attribute to the <div class="gcse-searchresults"></div> element on your website so that it looks like as given below.

<div class="gcse-searchbox"></div> <div class="gcse-searchresults" data-defaultToImageSearch="true"></div>

A few sample scripts

Search Script for using the custom search provided by Google:

  (function() {
    var cx = 'google-custom-search-engine-id';
    var gcse = document.createElement('script');
    gcse.type = 'text/javascript';
    gcse.async = true;
    gcse.src = '' + cx;
    var s = document.getElementsByTagName('script')[0];
    s.parentNode.insertBefore(gcse, s);

Search Script for using a custom search provided by Expertrec: 

In the code below, replace YOUR_API_KEY with your API key from here.

(function() {
var id = 'YOUR_API_KEY';
var ci_search = document.createElement('script');
ci_search.type = 'text/javascript';
ci_search.async = true;
ci_search.src = '' + id;
var s = document.getElementsByTagName('script')[0];
s.parentNode.insertBefore(ci_search, s);


The above code should be copied to an <div> element in your site’s <body> section, where you want both of the search box and the search results to render.

After the addition of the JavaScript code to the source HTML code of the web page, it will have a search bar to handle search queries and display them accordingly. More on this is covered in Google custom search, Bing custom search, Expertrec custom search.

In summary, Search functionality is at the center of this digital world. People are going to interact with your site and it should be easy to find what they are looking for in their terms. Internal site search is a must-have feature as content and users of your website grow. There are numerous options as discussed above while adding site searches to the website.
