如何确定apachesolr是否返回空结果

Question

如果apachesolr在单独的模块中为搜索查询返回空结果，我正在寻找执行一些代码。我期待离开apachesolr模块和acquia模块不变。

基本上你只覆盖theme_box功能的te​​mplate.php在你的主题，并检查标题和内容匹配默认“无结果”模板。

我最终什么了：

function mytheme_box($title, $content, $region = 'main') { 
    if ($title == t('Your search yielded no results') && 
     $content == variable_get('apachesolr_search_noresults', apachesolr_search_noresults())) { 
    if ($_GET['fuzzyhelp']) { 
     // No results with fuzzy, go to landing page for no results. 
     drupal_goto('search_no_results'); 
    } 

    // Rewrite search keys with fuzzy characters. 
    $keys = array_map('trim', explode(' ', search_get_keys())); 
    drupal_goto('search/apachesolr_search/'. implode('~ ', $keys). '~', 'fuzzyhelp=1');  
    } 
    else if ($_GET['fuzzyhelp']) { 
    // Tell user search was rewritten with fuzzy notations. 
    drupal_set_message(t('Your exact search did not match any products and was broadened to include all possible matches.')); 
    } 

    return $content; 
}
