Solr Facet查询 [英] Solr Facet Query

问题描述

我有一个模式，该模式的字段Polarity的类型为文本"，并且具有三个值0,1，-1和CreatedAt的类型为"date".

I have a schema which has field Polarity which is of type "text" and has three values 0,1,-1 and CreatedAt which is of type "date".

如何获取基于日期的每种极性的计数.例如，它给出的输出是，在2011年5月1日，有10个计数为0、10个计数为1和10个计数为-1

How can I get count of each polarity based on dates. For example, it gives the output that on 5/1/2011 there were 10 counts of 0, 10 counts of 1 and 10 counts of -1

推荐答案

稍晚一些，但可能会帮助其他人寻找答案.

A little late but may help others looking for an answer.

我建议检查Solr 枢轴，以检查这种分层构面.
您可以将日期和极性作为第二个方面，以在该日期内获取结果.

I would suggest check for Solr pivots for this kind of hierarchical faceting.
You can facet on the dates and the polarity as secondary facet to get results within the date.
