What is faceted search?
提问by Gnanam
What exactly is faceted searchin the context of full-text search?
在全文搜索的上下文中，分面搜索究竟是什么？
I even read about it from Wikipedia, but I couldn't completely understand the use/benefit of it. Hope the community can answer/expand and explain with some good examples.
我什至从Wikipedia 上读到了它，但我无法完全理解它的用途/好处。希望社区可以回答/扩展并用一些好的例子来解释。
NOTE:We're into the process of evaluating/researching different open search full-text search engine and mostly I'm seeing faceted searchlisted as one of the feature among others. So I'm trying to assess whether this would be helpful for our application requirement.
注意：我们正在评估/研究不同的开放式搜索全文搜索引擎，而且我主要看到分面搜索被列为其中一项功能。所以我正在尝试评估这是否对我们的应用程序要求有帮助。

Faceted (or navigational) search uses a hierarchy structure (taxonomy) to enable users to browse information by choosing from a pre-determined set of categories. This allows a user to type in their simple query, then refine their search options by navigating/drilling down. In reality, it's an advanced search going on in the background, but instead of the user having to think of the additional search categories, it's been made easier for them by the visible folder structure. Examples of this are eCommerce sites like Amazon and eBay.
分面（或导航）搜索使用层次结构（分类法）使用户能够通过从一组预先确定的类别中进行选择来浏览信息。这允许用户输入他们的简单查询，然后通过导航/向下钻取来优化他们的搜索选项。实际上，这是在后台进行的高级搜索，但用户不必考虑其他搜索类别，可见的文件夹结构使他们更容易。这方面的例子是亚马逊和 eBay 等电子商务网站。

Faceted search is technically a guided navigation which allows the users to narrow down their search results. It can be used in big directories (like an image library for example), but the most common use of this search feature is for eCommerce web shops / web stores. Here is a fresh and comprehensive articleabout what is faceted search and how it works - I hope it helps.
分面搜索在技术上是一种引导式导航，允许用户缩小搜索结果的范围。它可用于大目录（例如图像库），但此搜索功能最常用于电子商务网上商店/网上商店。这是一篇关于什么是分面搜索及其工作原理的新鲜而全面的文章- 我希望它有所帮助。
