Это просто трюк, а не неправильный способ, но вы можете попробовать.

Сначала вы должны записать запрос Solr, который выполняется при нажатии search.

Я использую модуль уровня solr для перехвата запроса. Затем создайте свой собственный модуль с хуками.

 /**
 * Implements hook_menu().
*/
function mymodule_menu() {
    $items = array();

    //create a call back for autocomplete search box
    $items['searchauto/autocomplete'] = array(
        'page callback' => 'mymodule_search_autocomplete',
        //'access arguments' => array('access search autocomplete'),
        'type' => MENU_CALLBACK,
        'access arguments' => array('access content'),
    );

    return $items;
}

/**
* hook_form_FORM_ID_alter
* solr search form text box autocomplete
**/
function mymodule_form_search_block_form_alter(amp;$form, amp;$form_state, $form_id) {

    $form['search_block_form'] = array(
        '#type' => 'textfield',
        '#autocomplete_path' => 'searchauto/autocomplete',
    );
}

/**
* call back function for autocomplete
**/
function mymodule_search_autocomplete($string) {

    unset($results);
    $results = array();
    $matches = array();

    //replace the space with  
    $key = preg_replace('/[[:space:]] /', ' ', $string);
    //number of results you want to show
    $num_result = 15;
    //your Solr server path
    $solr_server = "http://locathost/solr";

    //this is the trick. first you should capture the Solr query, which executed when you hit search. I use the Solr level module to catch the query. you can change parameters if you want, I'm only changing the search keyword and number of results

        }

            //loop the results and add to array for json return data

                $matches[$row->url] = $row->label;
