Usage

Now you have all indexes registered and you want to uses them, really easy!, _(*2)

in a controller for example :, _(*3)

/**
 * @param Request $request
 * @return array
 * @Route("/search", name="path_search")
 * @Template()
 * @Method({"GET", "POST"})
 */
public function searchAction(Request $request) {
    $results = null;
    if ($request->request->has('term') and '' !== $request->request->get('term')) {
        $results = $this->get('lpi_lucene.search')->search($request->request->get('term'));
    }

    return array(
        'results' => $results
    );
}

and the render in your view for example:, _(*4)

{% if results is defined and results|length > 0 %}
    {% for result in results %}
        <div class="col-xs-12">
            <a href="{{ result.url }}" title="{{ result.title }}">
                {{ result.title }}
            </a>
