mysql - cakephp 在具有多个搜索关键字的单列上查询 find_in_set 不起作用

Question

我想从列中查找与列数据有任何关键字匹配的所有记录:

如果在具有逗号分隔值的列中搜索单个搜索关键字，则效果很好，如下代码:Cakephp 3.4 版本

$posts = TableRegistry::get('Posts');
                $search_keywords = array_filter(explode(' ', $search_string));
                $option = [
                      'contain' => false,
                      'conditions' => [
                        "find_in_set('New', Posts.title)",
                      ],
                      'order' => ['Posts.created DESC'] 
                  ];
        $allpost = $posts->find('all',$option)->toArray();

注意:我希望字符串中的所有单词都应该使用列标题进行搜索，不强制要求有逗号分隔的记录:

$search_keyword = "New car in new delhi";

所以我希望代码如下:

$search_keyword = "New car in new delhi";
$search_keywords = array_filter(explode(' ', $search_string));
                $option = [
                      'contain' => false,
                      'conditions' => [
                        "find_in_set({$search_keywords}, `Posts`.title)",
                      ],
                      'order' => ['Posts.created DESC'] 
                  ];
        $allpost = $posts->find('all',$option)->toArray();

非常感谢!

我找到了解决方案:

首先创建列全文索引，然后添加以下代码:

$search_string = "New car in new delhi";
$option = [
                      'contain' => false,
                      'conditions' => [
                        "MATCH (title) AGAINST ('$search_string')"
                      ],
                      'order' => ['Posts.created DESC'] 
                  ];
        $allpost = $posts->find('all',$option)->toArray();
