分面搜索的问题

Question

我正在做一些分面搜索,但有一些问题.当分面搜索字段中有多个单词时,我无法获得所需的结果.

示例:"animal"字段,包含以下条目:

        A horse

        Black horse

        Black horse

La faceted搜索发回"horse(3)"作为最佳结果,而我想回到"Black horse(2)".

这是schema.xml.搜索字段是BUSQUEDA,分面字段是SUPERFICIE.我想我已经尝试了这两个字段的大多数已定义类型的可能组合,但仍然不起作用.

有什么建议？

提前谢谢!

您必须在非标记化字段（字段类 solr.StrField 或使用 solr.KeywordTokenizerFactory）上进行分面。这个线程详细解释了它。
