This bundle provides a uniform interface for full text search with various search engines and a controller with twig templates to render search forms and results.

Note: You are looking at Version 2 of this bundle, which saw large changes compared to Version 1.


This search bundle simplifies adding search to your site.

Provided for you are:

  • A controller to render a search box and the search page with twig templates
  • A service to query google site search
  • A service which provides paging for the search results

Built-in Search Engines Support

For now, Google site search is supported out of the box. There is one implementation using the Google REST API and one implementation using the Custom Search Element feature that loads the search with only javascript in the frontend.

Contributions for other services are welcome.


Install the bundle with composer require liip/search-bundle.

Include the bundle in app/Kernel.php.

Add your preferred search engine in app/config/config.yml:

            api_key: '%google.api_key%'
            search_key: '%google.search_key%'

Or if you use the javascript Google custom search engine:

            cse_id: '%google.search_key%'


You can display a search box anywhere on the page with the liip_search_box twig function:

{{ liip_search_box(query, 'query-field-id', 'css-class') }}

You can customize the search box with these parameters:

  • query - default query to display
  • fieldId - HTML id to use for the search input field. Use different ids when having more than one search box on your page, e.g. in the header and in content.
  • cssClass - A css class to apply to the whole search box <form>.

Create a route for the search action. The easiest is to just use the provided routing.xml from your main project routing.xml:

        resource: "@LiipSearchBundle/Resources/config/routing.xml"

It defaults to the URL /search. If you want a different route, use the prefix option when including the route or configure your own route using %liip_search.controller.search_action% as default value for _controller.

Customizing Templating

The search result templates provided by this bundle extend the LiipSearchBundle::layout.html.twig template. To integrate with the rest of your site, you have two options:

  • Create app/Resources/LiipSearchBundle/views/layout.html.twig and make it extend your base layout, putting a liip_search_content block where you want the search results.
  • Create app/Resources/LiipSearchBundle/views/Search/search.html.twig and build your own templating structure - you should be able to use the search_results.twig.html template to get the liip_search_content block.

Of course you can also override any of the templates to customize what they should do. See

Configuration Reference

This is the full reference of what you can configure under the liip_search key:


string, default value: null

Specify a custom service that implements the Liip\SearchBundle\SearchFactoryInterface. This service will be used by the controller to create Pagerfanta instances to handle the search.

If you configure one of the search engine services, you do not need to set this field.


string, default value: liip_search

The name of the route that will handle submitted search requests.


boolean, default value: false

Change this to true if you want to ask the search service to restrict the results to the language of the request.

Google Search REST API Integration

Configuring any of these options enables the google search engine service. They are located under clients.google_rest.


string, required

Your Google API key


string|array, required

The key identifying your Google Search Engine. May be a list of keys indexed by locale to use different engines per locale. If you control locales through separate search engines, you do not need to set restrict_language to true unless you want your custom search engines to receive a language restriction additionally.


string, default value:

The Google Search API URL for REST calls


string, default value: null

If left empty, all sites configured for the google search engines are searched. Set to a a domain to limit to that domain.

Google Custom Search Engine Integration

Configuring this section activates a different controller that renders the Javascript fragment to enable the CSE search. This configuration is located under clients.google_cse.


string|array, required

The key identifying your Google Custom Search Engine. May be a list of keys indexed by locale to use different engines per locale. CSE does not support the restrict_language, so different search engines per language are your only option to restrict the language of search results.


Google Custom Search Engine

If you get SearchException saying "Empty response received from Google Search Engine API", try copying the URL that is output into a browser. You should get JSON response, but likely it will haves an error status.

If you get a status 500 with an empty message, chances are that you need to renew the search engine in the Google admin panel.

Adding your own Search Service

Implement the Liip\SearchBundle\SearchInterface and configure it as a service. Then set liip_search.search_client to that service name.


  • Use guzzle to talk to google REST API
  • Add support for refinements (more like this) with info in search result array that can be passed to SearchInterface::refineSearch
  • Expose more of the google search parameters
