我在去年年底使用DataObjects as Pages - Part 2 Silverstripe创建了一个产品网站，该网站现已上线，我需要为该网站实施网站搜索功能。
我实现了像Tutorial 4 - Site Search这样的搜索功能，但是这不适用于产品搜索，因为每个产品都是数据对象而不是页面。
任何人都可以了解我如何使网站搜索工作的产品？
我知道有一个tutorial 3 DataObject as Pages我尝试了它但它搞砸了我现有的所有产品以及产品的一些其他现有功能。有人建议http://silverstripe.org/all-other-modules/show/6641?start=24但到目前为止都没有成功。
有关如何为产品执行搜索功能的任何帮助表示赞赏。
感谢。
这是我的Product.php代码

如果您正在进行任何严肃的搜索工作，内置搜索功能（基于MySQL MyISAM）并不理想。我建议使用Solr或Sphinx，将其与https://github.com/silverstripe/silverstripe-sphinx或https://github.com/nyeholt/silverstripe-solr集成到SilverStripe中（我从第一个开始）。这也将为DAO编制索引。
