什么是分面搜索？
全文搜索上下文中的分面搜索到底是什么？
我什至从维基百科读到它，但我不能完全了解它的用途/好处。希望社区能够回答/扩展并用一些好的例子进行解释。
注意：我们正在评估/研究不同的开源全文搜索引擎，大多数情况下我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要求有帮助。
What exactly is faceted search in the context of full-text search?
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.
NOTE: We're into the process of evaluating/researching different open source full-text search engine and mostly I'm seeing faceted search listed as one of the feature among others. So I'm trying to assess whether this would be helpful for our application requirement.

分面搜索有很好的解释 此处 和 Lucene 分面 通过示例。
示例：
Faceted search is well-explained here and Lucene faceted through an example.
EXAMPLE:
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。这允许用户输入简单的查询，然后通过导航/向下钻取来优化搜索选项。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用户变得更容易。亚马逊和 eBay 等电子商务网站就是这样的例子。
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.
分面搜索从技术上讲是一种引导式导航，允许用户缩小搜索结果范围。它可以在大目录中使用（例如图像库），但此搜索功能最常见的用途是电子商务网上商店/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且全面的文章 -我希望它有帮助。
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 article about what is faceted search and how it works - I hope it helps.
Facet 已成为在线搜索的核心。这称为分面搜索 - 其中类别和常用术语与搜索栏中的文本一样推动搜索。
他们的技术实施也有好处。查看这篇关于如何使用 JSON 创建分面搜索：
Facets have become central to online search. It’s called faceted search - where categories and common terms drive the search just as much as the text in a search bar.
Their technical implementation also has benefits. Check out this article on How to use JSON to create a faceted search:
