Silverstripe Site Search for DataObjects as Pages - 第 2 部分教程

Question

去年年底我用DataObjects as Pages - Part 2Silverstripe做了一个产品站点，站点已经上线，我需要为站点实现站点搜索功能。

我实现了一个像Tutorial 4 - Site Search 这样的搜索功能，但这不适用于产品搜索，因为每个产品都是一个数据对象而不是一个页面。

谁能解释我如何使网站搜索适用于产品？

我知道有一个tutorial 3 DataObject as Pages 我试过了，但它弄乱了我所有现有的产品以及产品的一些额外现有功能。有人建议http://silverstripe.org/all-other-modules/show/6641?start=24，但目前没有成功。

感谢任何有关如何为产品执行搜索功能的帮助。

谢谢。

这是我的Product.php 代码

<?php

    static $db = array(
        'Title' => 'Varchar(255)',

如果您正在做任何严肃的搜索，内置的搜索功能（基于 MySQL MyISAM）并不理想。我建议使用 Solr 或 Sphinx，通过 https://github.com/silverstripe/silverstripe-sphinx 或 https://github.com/nyeholt/silverstripe-solr 集成到 SilverStripe 中（我将从第一个开始）。这也将索引 DAO。
