在 Solr 中进行分层分面的方法? [英] Ways to do hierarchial faceting in Solr?

问题描述

如果文档被列为 Book>Fiction>Sci-fi，则当您的构面查询为Book"、Book>Fiction"、Book>Fiction>Sci-fi"时，它必须是可搜索的.

If a doc is listed as Book>Fiction>Sci-FI, it must be searchable when your facet query is "Book", "Book>Fiction", "Book>Fiction>Sci-fi".

上网查了一下，想到的方法是:

I searched the Internet and the methods I came up with are:

1 在索引时间将Book>Fiction>Sci-fi"拆分为Book"、Book>Fiction"、Book>Fiction>Sci-fi"并存储它们在同一领域.

1 Split the "Book>Fiction>Sci-FI" into "Book", "Book>Fiction", "Book>Fiction>Sci-fi" at index-time itself and store them in same field.

2 有单独的字段 cat、sub_cat、sub_sub_cat.将类别拆分为相应的字段并使用 Pivot facets http://wiki.apache.org/solr/SimpleFacetParameters#Pivot_.28ie_Decision_Tree.29_Faceting

2 Have separate fields cat, sub_cat, sub_sub_cat. Split the catogories into corresponding fields and use Pivot facets http://wiki.apache.org/solr/SimpleFacetParameters#Pivot_.28ie_Decision_Tree.29_Faceting

还有哪些其他方法可以处理层次分面，以便它们可以支持任何复杂的查询?
